# 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.com/creating-go-actions/).
|
|
|
|
### Support the non-standard syntax @yearly, @monthly, @weekly, @daily, @hourly on schedule
|
|
|
|
Github Actions doesn't support that. https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#schedule
|
|
|
|
## 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
|
|
|
|
### 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.
|
|
|
|
### Services steps
|
|
|
|
Services steps don't have their own section in the job log user interface.
|
|
|
|
## Different behavior
|
|
|
|
### Downloading actions
|
|
|
|
Previously (Pre 1.21.0), `[actions].DEFAULT_ACTIONS_URL` defaulted to `https://gitea.com`.
|
|
We have since restricted this option to only allow two values (`github` and `self`).
|
|
When set to `github`, the new default, Gitea will download non-fully-qualified actions from `https://github.com`.
|
|
For example, if you use `uses: actions/checkout@v3`, it will download the checkout repository from `https://github.com/actions/checkout.git`.
|
|
|
|
If you want to download an action from another git hoster, you can use an absolute URL, e.g. `uses: https://gitea.com/actions/checkout@v3`.
|
|
|
|
If your Gitea instance is in an intranet or a restricted area, you can set the URL to `self` to only download actions from your own instance by default.
|
|
Of course, you can still use absolute URLs in workflows.
|
|
|
|
More details about the `[actions].DEFAULT_ACTIONS_URL` configuration can be found in the [Configuration Cheat Sheet](administration/config-cheat-sheet.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).
