# Go on Docker Swarm
|
|
|
|
|
|
|
|
[Particubes](https://particubes.com) is a platform dedicated to voxel games, which are games made out of little cubes, like Minecraft.
|
|
The team consists of 10 developers that like to keep things simple.
|
|
They write primarily Go & Lua, push to GitHub and use GitHub Actions for automation.
|
|
The production setup is a multi-node Docker Swarm cluster running on AWS.
|
|
|
|
The Particubes team chose Dagger for continuous deployment because it was the easiest way of integrating GitHub with Docker Swarm.
|
|
Every commit to the main branch goes straight to [docs.particubes.com](https://docs.particubes.com) via a Dagger pipeline that runs in GitHub Actions. Let us see how the Particubes Dagger plan fits together.
|
|
|
|
## Actions API
|
|
|
|
This is a high level overview of all actions in the Particubes docs Dagger plan:
|
|
|
|
|
|
|
|
We can see all available actions in a Plan by running the following command:
|
|
|
|
```console
|
|
$ dagger do
|
|
Execute a dagger action.
|
|
|
|
Available Actions:
|
|
build Create a container image
|
|
clean Remove a container image
|
|
test Locally test a container image
|
|
deploy Deploy a container image
|
|
```
|
|
|
|
## Client API
|
|
|
|
Dagger actions usually need to interact with the host environment where the Dagger client runs. The Particubes' plan uses environment variables and the filesystem.
|
|
|
|
This is an overview of all client interactions for this plan:
|
|
|
|
|
|
|
|
This is what the above looks like in the Dagger plan config:
|
|
|
|
```cue file=../tests/use-cases/go-docker-swarm/client-api.cue.fragment
|
|
|
|
```
|
|
|
|
## The `build` Action
|
|
|
|
This is a more in-depth overview of the _build_ action and how it interacts with the client in the Particubes docs Dagger plan:
|
|
|
|
|
|
|
|
This is what the above looks like in the Dagger plan config:
|
|
|
|
```cue file=../tests/use-cases/go-docker-swarm/build-action.cue.fragment
|
|
|
|
```
|
|
|
|
## GitHub Action integration
|
|
|
|
This is the GitHub Actions workflow config that invokes `dagger`, which in turn runs the full plan:
|
|
|
|
```yaml
|
|
name: Dagger/docs.particubes.com
|
|
|
|
on:
|
|
push:
|
|
branches: [master]
|
|
|
|
jobs:
|
|
deploy:
|
|
runs-on: ubuntu-latest
|
|
env:
|
|
GITHUB_SHA: ${{ github.sha }}
|
|
SSH_PRIVATE_KEY_DOCKER_SWARM: ${{ secrets.SSH_PRIVATE_KEY_DOCKER_SWARM }}
|
|
steps:
|
|
- name: Checkout code
|
|
uses: actions/checkout@v3
|
|
|
|
- name: Install Dagger
|
|
uses: dagger/dagger-action@v2
|
|
with:
|
|
install-only: true
|
|
|
|
- name: Dagger project update
|
|
run: dagger project update
|
|
|
|
- name: Dagger do test
|
|
run: dagger do test --log-format plain
|
|
|
|
- name: Dagger do deploy
|
|
run: dagger do deploy --log-format plain
|
|
```
|
|
|
|
Since this is a Dagger pipeline, anyone on the team can run it locally with a single command:
|
|
|
|
```console
|
|
dagger do
|
|
```
|
|
|
|
This is the first step that enabled the Particubes team to have the same CI/CD experience everywhere.
|
|
|
|
## Full Particubes docs Dagger plan
|
|
|
|
This is the entire plan running on Particubes' CI:
|
|
|
|
```cue file=../tests/use-cases/go-docker-swarm/full/particubes.docs.cue
|
|
|
|
```
|
|
|
|
## What comes next ?
|
|
|
|
Particubes' team suggested that we create a `dev` action with _hot reload_, that way Dagger would even asbtract away the ramp-up experience when developing the doc
