Docusaurus-ify (#26051)
This PR cleans up the docs in a way to make them simpler to ingest by
our [docs repo](https://gitea.com/gitea/gitea-docusaurus).

1. It includes all of the sed invocations our ingestion did, removing
the need to do it at build time.
2. It replaces the shortcode variable replacement method with
`@variable@` style, simply for easier sed invocations when required.
3. It removes unused files and moves the docs up a level as cleanup.

Compared to GitHub Actions

Even though Gitea Actions is designed to be compatible with GitHub Actions, there are some differences between them.

Additional features

Absolute action URLs

Gitea Actions supports defining actions via absolute URL, which means that you can use actions from any git repository. Like uses: https://github.com/actions/checkout@v3 or uses: http://your_gitea.com/owner/repo@branch.

Actions written in Go

Gitea Actions supports writing actions in Go. See Creating Go Actions.

Unsupported workflows syntax

concurrency

It's used to run a single job at a time. See Using concurrency.

It's ignored by Gitea Actions now.

run-name

The name for workflow runs generated from the workflow. See Workflow syntax for GitHub Actions.

It's ignored by Gitea Actions now.

permissions and jobs.<job_id>.permissions

See Workflow syntax for GitHub Actions.

It's ignored by Gitea Actions now.

jobs.<job_id>.timeout-minutes

See Workflow syntax for GitHub Actions.

It's ignored by Gitea Actions now.

jobs.<job_id>.continue-on-error

See Workflow syntax for GitHub Actions.

It's ignored by Gitea Actions now.

jobs.<job_id>.environment

See Workflow syntax for GitHub Actions.

It's ignored by Gitea Actions now.

Complex runs-on

See Workflow syntax for GitHub Actions.

Gitea Actions only supports runs-on: xyz or runs-on: [xyz] now.

workflow_dispatch

See Workflow syntax for GitHub Actions.

It's ignored by Gitea Actions now.

hashFiles expression

See Expressions

Gitea Actions doesn't support it now, if you use it, the result will always be empty string.

As a workaround, you can use go-hashfiles instead.

Missing features

Variables

See Variables.

It's under development.

Problem Matchers

Problem Matchers are a way to scan the output of actions for a specified regex pattern and surface that information prominently in the UI. See Problem matchers.

It's ignored by Gitea Actions now.

Create an error annotation

See Creating an annotation for an error

It's ignored by Gitea Actions now.

Missing UI features

Pre and Post steps

Pre and Post steps don't have their own section in the job log user interface.

Different behavior

Downloading actions

Gitea Actions doesn't download actions from GitHub by default. "By default" means that you don't specify the host in the uses field, like uses: actions/checkout@v3. As a contrast, uses: https://github.com/actions/checkout@v3 has specified host.

The missing host will be filled with https://gitea.com if you don't configure it. That means uses: actions/checkout@v3 will download the action from gitea.com/actions/checkout, instead of github.com/actions/checkout.

As mentioned, it's configurable. If you want your runners to download actions from GitHub or your own Gitea instance by default, you can configure it by setting [actions].DEFAULT_ACTIONS_URL. See Configuration Cheat Sheet.

Context availability

Context availability is not checked, so you can use the env context on more places. See Context availability.

Known issues

docker/build-push-action@v4

See act_runner#119.

ACTIONS_RUNTIME_TOKEN is a random string in Gitea Actions, not a JWT. But the docker/build-push-action@v4 tries to parse the token as JWT and doesn't handle the error, so the job fails.

There are two workarounds:

Set the ACTIONS_RUNTIME_TOKEN to empty manually, like:

- name: Build and push
  uses: docker/build-push-action@v4
  env:
    ACTIONS_RUNTIME_TOKEN: ''
  with:
...

The bug has been fixed in a newer commit, but it has not been released. So you could use the latest version by specifying the branch name, like:

- name: Build and push
  uses: docker/build-push-action@master
  with:
...
