# 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](https://blog.gitea.io/2023/04/creating-go-actions/).
|
|
|
|
## Unsupported workflows syntax
|
|
|
|
### `concurrency`
|
|
|
|
It's used to run a single job at a time.
|
|
See [Using concurrency](https://docs.github.com/en/actions/using-jobs/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](https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#run-name).
|
|
|
|
It's ignored by Gitea Actions now.
|
|
|
|
### `permissions` and `jobs.<job_id>.permissions`
|
|
|
|
See [Workflow syntax for GitHub Actions](https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#permissions).
|
|
|
|
It's ignored by Gitea Actions now.
|
|
|
|
### `jobs.<job_id>.timeout-minutes`
|
|
|
|
See [Workflow syntax for GitHub Actions](https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idtimeout-minutes).
|
|
|
|
It's ignored by Gitea Actions now.
|
|
|
|
### `jobs.<job_id>.continue-on-error`
|
|
|
|
See [Workflow syntax for GitHub Actions](https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idcontinue-on-error).
|
|
|
|
It's ignored by Gitea Actions now.
|
|
|
|
### `jobs.<job_id>.environment`
|
|
|
|
See [Workflow syntax for GitHub Actions](https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idenvironment).
|
|
|
|
It's ignored by Gitea Actions now.
|
|
|
|
### Complex `runs-on`
|
|
|
|
See [Workflow syntax for GitHub Actions](https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idruns-on).
|
|
|
|
Gitea Actions only supports `runs-on: xyz` or `runs-on: [xyz]` now.
|
|
|
|
### `workflow_dispatch`
|
|
|
|
See [Workflow syntax for GitHub Actions](https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#onworkflow_dispatch).
|
|
|
|
It's ignored by Gitea Actions now.
|
|
|
|
### `hashFiles` expression
|
|
|
|
See [Expressions](https://docs.github.com/en/actions/learn-github-actions/expressions#hashfiles)
|
|
|
|
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](https://gitea.com/actions/go-hashfiles) instead.
|
|
|
|
## Missing features
|
|
|
|
### Variables
|
|
|
|
See [Variables](https://docs.github.com/en/actions/learn-github-actions/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](https://github.com/actions/toolkit/blob/main/docs/problem-matchers.md).
|
|
|
|
It's ignored by Gitea Actions now.
|
|
|
|
### Create an error annotation
|
|
|
|
See [Creating an annotation for an error](https://docs.github.com/en/actions/using-workflows/workflow-commands-for-github-actions#example-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](https://gitea.com/actions/checkout), instead of [github.com/actions/checkout](https://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]({{< relref "doc/administration/config-cheat-sheet.en-us.md#actions-actions" >}}).
|
|
|
|
### Context availability
|
|
|
|
Context availability is not checked, so you can use the env context on more places.
|
|
See [Context availability](https://docs.github.com/en/actions/learn-github-actions/contexts#context-availability).
|
|
|
|
## Known issues
|
|
|
|
### `docker/build-push-action@v4`
|
|
|
|
See [act_runner#119](https://gitea.com/gitea/act_runner/issues/119#issuecomment-738294).
|
|
|
|
`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:
|
|
|
|
``` yml
|
|
- name: Build and push
|
|
uses: docker/build-push-action@v4
|
|
env:
|
|
ACTIONS_RUNTIME_TOKEN: ''
|
|
with:
|
|
...
|
|
```
|
|
|
|
The bug has been fixed in a newer [commit](https://gitea.com/docker/build-push-action/commit/d8823bfaed2a82c6f5d4799a2f8e86173c461aba?style=split&whitespace=show-all#diff-1af9a5bdf96ddff3a2f3427ed520b7005e9564ad), but it has not been released. So you could use the latest version by specifying the branch name, like:
|
|
|
|
``` yml
|
|
- name: Build and push
|
|
uses: docker/build-push-action@master
|
|
with:
|
|
...
|
|
```
