Cup was created to be simple. The data is there, and it's up to you to retrieve it (e.g. by running `cup check -r` with a cronjob or periodically requesting the `/api/v3/json` url from the server).

This is where Cup's documentation lives. It's created with [Nextra](https://nextra.site). # Cup Documentation
## Architecture
The docs are built with [Nextra](https://nextra.site). We use [Bun](https://bun.sh) as a package manager and Node.js as a runtime (Next.js and Bun don't play well together at the moment). Docs pages are written in [MDX](https://mdxjs.com) and any custom components are written in TypeScript with TSX.
## Development
Prerequisites:
- A recent Node.js version (22 recommended)
- [Bun](https://bun.sh)
```bash
git clone https://github.com/sergi0g/cup
cd cup/docs
bun install
```
You're ready to go!
## Scripts
The available scripts are:
- `bun dev` starts the development server. Note that making changes to MDX pages will probably require a full reload.
- `bun run build` creates a static production build, ready to be deployed.
- `bun lint` checks for errors in your code.
- `bun fmt` formats your code with Prettier, so it becomes... prettier.
## Contributing
Our documentation is always evolving, so, we constantly need to update this repository with new guides and configuration options. If you have any ideas of a guide or suggestions on how to improve them, feel free to open a pull request or create an issue. All contributions are welcome!
## License

# About
Cup is a small utility that checks for updates to Docker containers. The logic is simple: Cup checks the locally pulled images' digests against the latest ones in their registry. It then presents the results in a pretty interface. Here's the story:
## How it started
I got the basic idea for Cup a long time ago. I was looking at [Homepage's list of widgets](https://gethomepage.dev/latest/widgets/) when I discovered [What's Up Docker?](https://github.com/getwud/wud) (referred to as WUD from now on).
According to the docs:
> What's up Docker ( aka WUD ) gets you notified when a new version of your Docker Container is available.
It supports the most common registries, has integrations with IFTTT, Slack, Telegram and other apps/services for notifications or triggering workflows and also has the option to automatically update containers, like [Watchtower](https://github.com/containrrr/watchtower).
I was managing my homelab myself at that time and the only way to check if I had updates was log in to the server and manually try to pull the images for *every single compose file*. WUD seemed to solve the problem nicely, so I decided to give it a try. I never used automatic updates or notifications, but I configured it and let it run.
After deploying it and setting up my reverse proxy, I was greeted with this dashboard:
<Image src="https://github.com/getwud/wud/blob/master/docs/ui/ui.png?raw=true" alt="A screenshot of WUD's web UI, from the docs" />
It was working fine, but... the UI was not what I expected. It really reminds me of some really old Android app (I hope I didn't offend anyone). That was strike one. Nevertheless, I left it running. It was useful after all.
A few days later I was pulling some docker images, when I got this error message:
> You have reached your pull rate limit. You may increase the limit by authenticating and upgrading: https://www.docker.com/increase-rate-limits.
Wait a minute. What was that? I'd never encountered a message like this before. I thought "Weird. Maybe I pulled too many images today?". So I decided to finish those updates another day.
Next time I tried, same issue. "What the heck is happening?" I thought. The only change I'd made to my homelab at that time was installing WUD. So I stopped it. And that's where the problems ended.
The problem was clearly related to WUD, so I started trying to find what was going wrong. That was when I came upon [this page from Docker's documentation](https://docs.docker.com/docker-hub/download-rate-limit/). I noticed 2 things:
> A pull request is defined as up to two `GET` requests on registry manifest URLs (`/v2/*/manifests/*`)
> `HEAD` requests aren't counted.
There were also helpful instructions on how to check the rate limit:
```
sergio@desktop:~ $ TOKEN=$(curl "https://auth.docker.io/token?service=registry.docker.io&scope=repository:ratelimitpreview/test:pull" | jq -r .token)
% Total % Received % Xferd Average Speed Time Time Time Current

ratelimit-limit: 100;w=21600
ratelimit-remaining: 100;w=21600
docker-ratelimit-source: <REDACTED>
```
The rate limit is there, just like in the docs, but do you see something else interesting? Look at this header: `docker-content-digest: sha256:767a3815c34823b355bed31760d5fa3daca0aec2ce15b217c9cd83229e0e2020`
This is an image's digest. Can we check for updates by making `HEAD` requests to Docker Hub?
The answer is yes:
```
$ set TOKEN $(curl -H "Accept: application/vnd.docker.distribution.manifest.list.v2+json" "https://auth.docker.io/token?service=registry.docker.io&scope=repository:library/busybox:pull" | jq -r .token)
$ curl --head -H "Authorization: Bearer $TOKEN" -H "Accept: application/vnd.docker.distribution.manifest.v2.list+json" https://registry-1.docker.io/v2/library/busybox/manifests/latest
HTTP/1.1 200 OK
content-length: 6761
content-type: application/vnd.oci.image.index.v1+json
docker-content-digest: sha256:9ae97d36d26566ff84e8893c64a6dc4fe8ca6d1144bf5b87b2b85a32def253c7
docker-distribution-api-version: registry/2.0
etag: "sha256:9ae97d36d26566ff84e8893c64a6dc4fe8ca6d1144bf5b87b2b85a32def253c7"
date: Tue, 16 Jul 2024 12:17:49 GMT
strict-transport-security: max-age=31536000
ratelimit-limit: 100;w=21600
ratelimit-remaining: 100;w=21600
docker-ratelimit-source: <REDACTED>
```
And then we can compare that with the digest of the image stored locally:
```
$ docker inspect busybox:latest | jq -r '.[0].RepoDigests[0]'
busybox@sha256:9ae97d36d26566ff84e8893c64a6dc4fe8ca6d1144bf5b87b2b85a32def253c7
```
Notice how the 2 digests are the same. We can check for image updates without using up the rate limit!
That's when I got the idea of writing a program to do this automatically.
## The birth of Cup
I initially intended to write a simple bash script but I chose not to for the following reasons:
- I wanted something more than a simple script. WUD has a web UI and support for so many integrations! I had to match that some way!
- Bash is slow and I was learning Rust at the time, so I wanted to practice (and make a proper project)
It started out as a small CLI that could either check a single image, or check all the images.
<Image src={old_cup} alt="The initial version of Cup" />
It also couldn't check for updates to images not from Docker Hub, lacked a web UI and generally had many limitations. But it proved it could be done, quickly and efficiently. The binary was just 5 MB and took about 5 seconds for ~90 images on my development machine. That's insane!
A few days later, I decided to completely rewrite it. I tried to write clean code, split it in files and fix every limitation from the previous version. I'm quite close. Here's what it looks like now:
<Image src="https://github.com/sergi0g/cup/blob/main/screenshots/cup.gif?raw=true" alt="Cup's old CLI" />
It also has a statically rendered web UI making it ideal for self hosting.
<Image src={web_ui} alt="Cup's web UI"/>
With some optimization (well ok, maybe a lot), the binary is 5 MB and that means I finally don't have to wait forever to pull the Docker image! Finally something that works nicely with my 1.5 MB/s internet connection! (Thank you powerline!)
Now go ahead and try it out!

# Configuration
## Custom docker socket
Sometimes, there may be a need to specify a custom docker socket. Cup provides the `-s` option for this.
For example, if using Podman, you might do
```
$ cup -s /run/user/1000/podman/podman.sock check
```
This option is also available in the configuration file and it's best to put it there.
<Card icon={<IconPlug />} title="Custom Docker socket" href="/docs/configuration/socket" />
## Configuration file
Cup has an option to be configured from a configuration file named `cup.json`.
<Steps>
### Create the configuration file
Create a `cup.json` file somewhere on your system. For binary installs, a path like `~/.config/cup.json` is recommended.
If you're running with Docker, you can create a `cup.json` in the directory you're running cup and mount it into the container. _In the next section you will need to use the path where you **mounted** the file_
### Configure Cup from the configuration file
Follow the guides below to customize your `cup.json`
<Cards>
<Card icon={<IconKey />} title="Authentication" href="/docs/configuration/authentication" />
<Card icon={<IconLockOpen />} title="Insecure registries" href="/docs/configuration/insecure-registries" />
<Card icon={<IconPaint />} title="Theme" href="/docs/configuration/theme" />
</Cards>
Here's a full example:
```json
{
"authentication": {
"ghcr.io": "<YOUR_TOKEN_HERE>",
"registry-1.docker.io": "<YOUR_TOKEN_HERE>"
},
"theme": "blue",
"insecure_registries": ["localhost:5000", "my-insecure-registry.example.com"]
}
```
### Run Cup with the new configuration file
To let Cup know that you'd like it to use a custom configuration file, you can use the `-c` flag, followed by the _absolute_ path of the file.
```bash
$ cup -c /home/sergio/.config/cup.json check
```
```bash
$ docker run -tv /var/run/docker.sock:/var/run/docker.sock -v /home/sergio/.config/cup.json:/config/cup.json ghcr.io/sergi0g/cup -c /config/cup.json serve
```

# Insecure registries
For the best security, Cup only connects to registries over SSL (HTTPS) by default. However, for people running a local registry that haven't configured SSL, this may be a problem.
To solve this problem, `cup.json` has an `"insecure_registries"` option which allows you to specify exceptions
Here's what it looks like:
```json
{
"insecure_registries": ["<INSECURE_REGISTRY_1>", "<INSECURE_REGISTRY_2>"],
// Other options

Cup initially had a blue theme which looked like this:

This was replaced by a more neutral theme which is now the default:
<Image alt="Screenshot of neutral theme" src={gray} />
However, you can get the old theme back by adding the `theme` key to your `cup.json`
Available values are `default` and `blue`.

```
$ cup check -r
{"metrics":{"update_available":4,"monitored_images":25,"unknown":1,"up_to_date":20},"images":{"ghcr.io/immich-app/immich-server:v1.106.4":false,"portainer/portainer-ce:2.20.3-alpine":false,"ghcr.io/runtipi/runtipi:v3.4.1":false,...}}
```
Here is how it would look in Typescript:
```ts
interface CupData {
metrics: {
monitored_images: number,
up_to_date: number,
update_available: number,
unknown: number
},
images: {
[image: string]: boolean | null
}
}
```
## Usage with Docker
If you're using the Docker image, just replace all occurences of `cup` in the examples with `docker run -tv /var/run/docker.sock:/var/run/docker.sock ghcr.io/sergi0g/cup`.
For example, this:
```bash /check node:latest/
$ cup check node:latest
```
becomes:
```bash /check node:latest/
$ docker run -tv /var/run/docker.sock:/var/run/docker.sock ghcr.io/sergi0g/cup check node:latest
```

# Server
The server provides the `cup serve` command.
## Basic usage
```ansi
$ cup serve
2024-07-17T09:08:38.724922Z   INFO  xitca_server::net  :  Started Tcp listening on: Some(0.0.0.0:8000)
2024-07-17T09:08:38.725076Z   WARN  xitca_server::server::future  :  ServerFuture::wait is called from within tokio context. It would block current thread from handling async tasks
2024-07-17T09:08:38.725248Z   INFO  xitca_server::worker  :  Started xitca-server-worker-0
2024-07-17T09:08:38.725343Z   INFO  xitca_server::worker  :  Started xitca-server-worker-1
2024-07-17T09:08:38.725580Z   INFO  xitca_server::worker  :  Started xitca-server-worker-2
2024-07-17T09:08:38.725607Z   INFO  xitca_server::worker  :  Started xitca-server-worker-3
2024-07-17T09:08:41.390783Z   INFO  request  {  method  = GET uri  = / }  :  on_request  :  serving request
2024-07-17T09:08:41.390905Z   INFO  request  {  method  = GET uri  = / }  :  on_response  :  sending response
```
This will launch the server on port `8000`. To access it, visit `http://<YOUR_IP>:8000` (replace `<YOUR_IP>` with the IP address of the machine running Cup.)
<Callout>
The URL `http://<YOUR_IP>:8000/json` is also available for usage with integrations.
</Callout>
## Use a different port
Pass the `-p` argument with the port you want to use
```ansi
$ cup serve -p 9000
2024-07-17T09:08:38.724922Z   INFO  xitca_server::net  :  Started Tcp listening on: Some(0.0.0.0:9000)
2024-07-17T09:08:38.725076Z   WARN  xitca_server::server::future  :  ServerFuture::wait is called from within tokio context. It would block current thread from handling async tasks
2024-07-17T09:08:38.725248Z   INFO  xitca_server::worker  :  Started xitca-server-worker-0
2024-07-17T09:08:38.725343Z   INFO  xitca_server::worker  :  Started xitca-server-worker-1

2024-07-17T09:08:41.390783Z   INFO  request  {  method  = GET uri  = / }  :  on_request  :  serving request
2024-07-17T09:08:41.390905Z   INFO  request  {  method  = GET uri  = / }  :  on_response  :  sending response
```
## Usage with Docker
If you're using the Docker image, just replace all occurences of `cup` in the examples with `docker run -tv /var/run/docker.sock:/var/run/docker.sock -p <PORT>:<PORT> ghcr.io/sergi0g/cup`, where `<PORT>` is the port Cup will be using.
For example, this:
```bash /serve -p 9000/
$ cup serve -p 9000
```
becomes:
```bash /serve -p 9000/
$ docker run -tv /var/run/docker.sock:/var/run/docker.sock -p 9000:9000 ghcr.io/sergi0g/cup serve -p 9000
```

# Include/Exclude images
If you want to exclude some images (e.g. because they have too many tags and take too long to check), you can add the following to your config:
```jsonc
{
"images": {
"exclude": [
"ghcr.io/immich-app/immich-machine-learning",
"postgres:15"

// Other options

For an image to be excluded, it must start with one of the strings you specify above. That means you could use `ghcr.io` to exclude all images from ghcr.io or `ghcr.io/sergi0g` to exclude all my images (why would you do that?).
If you want Cup to always check some extra images that aren't available locally, you can modify your config like this:
```jsonc
{
"images": {
"extra": [
"mysql:8.0",
"nextcloud:30"
]

Note that you must specify images with version tags, otherwise Cup will exit with an error!

# Configuration
## Custom docker socket
Sometimes, there may be a need to specify a custom docker socket. Cup provides the `-s` option for this.
For example, if using Podman, you might do
```bash
$ cup -s /run/user/1000/podman/podman.sock check
```
This option is also available in the configuration file and it's best to put it there.
<Cards.Card
icon={<IconPlug />}
title="Custom Docker socket"
href="/docs/configuration/socket"
/>
## Configuration file
Cup has an option to be configured from a configuration file named `cup.json`.
<Steps>
### Create the configuration file
Create a `cup.json` file somewhere on your system. For binary installs, a path like `~/.config/cup.json` is recommended.
If you're running with Docker, you can create a `cup.json` in the directory you're running Cup and mount it into the container. _In the next section you will need to use the path where you **mounted** the file_
### Configure Cup from the configuration file
Follow the guides below to customize your `cup.json`

```json
{
"$schema": "https://raw.githubusercontent.com/sergi0g/cup/main/cup.schema.json",
"version": 3,
"images": {
"exclude": ["ghcr.io/immich-app/immich-machine-learning"],
"extra": ["ghcr.io/sergi0g/cup:v3.0.0"]
},
"registries": {
"myregistry.com": {
"authentication": "<YOUR_TOKEN_HERE>"
}
},
"servers": {
"Raspberry Pi": "https://server.local:8000"
},
"theme": "blue"
}
```
<Callout>
If you want autocompletions and error checking for your editor, there is a
JSON schema available. Use it by adding a `"$schema":
"https://raw.githubusercontent.com/sergi0g/cup/main/cup.schema.json"` entry in
your `cup.json` file.
</Callout>
### Run Cup with the new configuration file
To let Cup know that you'd like it to use a custom configuration file, you can use the `-c` flag, followed by the _absolute_ path of the file.
```bash
$ cup -c /home/sergio/.config/cup.json check
```
```bash
$ docker run -tv /var/run/docker.sock:/var/run/docker.sock -v /home/sergio/.config/cup.json:/config/cup.json ghcr.io/sergi0g/cup -c /config/cup.json serve

# Insecure registries
For the best security, Cup only connects to registries over SSL (HTTPS) by default. However, for people running a local registry that doesn't support SSL, this may be a problem.
To solve this problem, you can specify exceptions in your `cup.json`.
Here's what it looks like:
```jsonc
{
"registries": {
"<INSECURE_REGISTRY_1>": {
"insecure": true
// Other options
},
"<INSECURE_REGISTRY_2>" {

forget to specify the port (i.e. use `localhost:5000` instead of `localhost`
if your registry is running on port `5000`)

Besides checking for local image updates, you might want to be able to view update stats for all your servers running Cup in a central place.

Cup initially had a blue theme which looked like this:
<Image alt="Screenshot of blue theme" src={blue} />
This was replaced by a more neutral theme which is now the default:

# Integrations
At the moment, Cup has no built-in integrations, but it provides an API for the server and JSON output for the CLI, which can enable you to connect Cup to your own integrations.
## JSON data
The data returned from the API or from the CLI is in JSON and looks like this:
```jsonc
{
// Statistics useful for displaying on dashboards.
// You could calculate these yourself based on the rest of the data,
// but they're provided for easier integration with other systems.

// If `type` is "version":
"version_update_type": "major", // Loosely corresponds to SemVer versioning. Can also be `minor` or `patch`.
"new_tag": "v3.3.3", // The tag of the latest image.
},

},
"time": 869, // Time in milliseconds it took to check for the update. Useful for debugging.

```

Please keep in mind that the above may not always be up to date. New fields
may be added, or some types extended. If you notice that, just open an issue
and they'll be updated. Changes to the JSON data schema will _always_ happen
in a backwards-compatible way. In case backwards-incompatible changes are
made, these docs will be updated. For something more up-to-date, you can

# CLI
Cup's CLI provides the `cup check` command.
## Basic Usage
### Check for all updates
```ansi
$ cup check
✓ Done!

```
## Enable icons
You can also enable icons if you have a [Nerd Font](https://nerdfonts.com) installed.
<Image src={cup} alt="GIF of Cup's CLI" unoptimized />
## JSON output
When integrating Cup with other services (e.g. webhooks or a dashboard), you may find Cup's JSON output functionality useful.
It provides some useful metrics (see [server](/docs/usage/server) for more information), along with a list of images and whether they have an update or not. Note that at the moment it does not match the detailed API the server provides.
```
$ cup check -r
{"metrics":{"monitored_images":26,"up_to_date":2,"updates_available":23,"major_updates":8,"minor_updates":6,"patch_updates":2,"other_updates":7,"unknown":1},"images":{"ghcr.io/immich-app/immich-server:v1.106.4":false,"portainer/portainer-ce:2.20.3-alpine":false,"ghcr.io/runtipi/runtipi:v3.4.1":false,...}}
```
<Callout emoji="⚠️">
When parsing Cup's output, capture only `stdout`, otherwise you might not get
valid JSON (if there are warnings)
</Callout>
## Usage with Docker
If you're using the Docker image, just replace all occurences of `cup` in the examples with `docker run -tv /var/run/docker.sock:/var/run/docker.sock ghcr.io/sergi0g/cup`.
For example, this:
```bash
$ cup check node:latest
```
becomes:
```bash
$ docker run -tv /var/run/docker.sock:/var/run/docker.sock ghcr.io/sergi0g/cup check node:latest
```

# Server
The server provides the `cup serve` command.
## Basic usage
```ansi
$ cup serve
 INFO Starting server, please wait...
 INFO ✨ Checked 8 images in 8862ms
 INFO Ready to start!
 HTTP GET / 200 in 0ms
 HTTP GET /assets/index.js 200 in 3ms
 HTTP GET /assets/index.css 200 in 0ms
 HTTP GET /api/v3/json 200 in 0ms
```
This will launch the server on port `8000`. To access it, visit `http://<YOUR_IP>:8000` (replace `<YOUR_IP>` with the IP address of the machine running Cup.)
<Callout>
The URL `http://<YOUR_IP>:8000/api/v3/json` is also available for usage with integrations.
</Callout>
## Use a different port
Pass the `-p` argument with the port you want to use
```ansi
$ cup serve -p 9000
 INFO Starting server, please wait...
 INFO ✨ Checked 8 images in 8862ms
 INFO Ready to start!
 HTTP GET / 200 in 0ms
 HTTP GET /assets/index.js 200 in 3ms
 HTTP GET /assets/index.css 200 in 0ms
 HTTP GET /api/v3/json 200 in 0ms
```
## Usage with Docker
If you're using the Docker image, just replace all occurences of `cup` in the examples with `docker run -tv /var/run/docker.sock:/var/run/docker.sock -p <PORT>:<PORT> ghcr.io/sergi0g/cup`, where `<PORT>` is the port Cup will be using.
For example, this:
```bash
$ cup serve -p 9000
```
becomes:
```bash
$ docker run -tv /var/run/docker.sock:/var/run/docker.sock -p 9000:9000 ghcr.io/sergi0g/cup serve -p 9000
