# Multi pipelines
:::info
This Feature is only available for GitHub, Gitea & GitLab repositories. Follow [this](https://github.com/woodpecker-ci/woodpecker/issues/131) issue to support further development.
:::
By default, Woodpecker looks for the pipeline definition in `.woodpecker.yml` in the project root.
The Multi-Pipeline feature allows the pipeline to be split into several files and placed in the `.woodpecker/` folder. Only `.yml` files will be used and files in any subfolders like `.woodpecker/sub-folder/test.yml` will be ignored. You can set some custom path like `.my-ci/pipelines/` instead of `.woodpecker/` in the [project settings](./71-project-settings.md).
## Rational
- faster lint/test feedback, the pipeline doesn't have to run fully to have a lint status pushed to the remote
- better organization of the pipeline along various concerns: testing, linting, feature apps
- utilizing more agents to speed up build
## Example multi-pipeline definition
:::warning
Please note that files are only shared between steps of the same pipeline (see [File changes are incremental](./20-pipeline-syntax.md#file-changes-are-incremental)). That means you cannot access artifacts e.g. from the `build` pipeline below in the `deploy` pipeline.
If you still need to pass artifacts between the pipelines you need use storage [plugins](docs/usage/plugins/plugins) (e.g. one which stores files in an Amazon S3 bucket).
:::
```bash
.woodpecker/
├── .build.yml
├── .deploy.yml
├── .lint.yml
└── .test.yml
```
.woodpecker/.build.yml
```yaml
pipeline:
build:
image: debian:stable-slim
commands:
- echo building
- sleep 5
```
.woodpecker/.deploy.yml
```yaml
pipeline:
deploy:
image: debian:stable-slim
commands:
- echo deploying
depends_on:
- lint
- build
- test
```
.woodpecker/.test.yml
```yaml
pipeline:
test:
image: debian:stable-slim
commands:
- echo testing
- sleep 5
depends_on:
- build
```
.woodpecker/.lint.yml
```yaml
pipeline:
lint:
image: debian:stable-slim
commands:
- echo linting
- sleep 5
```
## Status lines
Each pipeline has its own status line on GitHub.
## Flow control
The pipelines run in parallel on separate agents and share nothing.
Dependencies between pipelines can be set with the `depends_on` element. A pipeline doesn't execute until its dependencies did not complete successfully.
The name for a `depends_on` entry is the filename without the path, leading dots and without the file extension `.yml`. If the project config for example uses `.woodpecker/` as path for ci files with a file named `.woodpecker/.lint.yml` the corresponding `depends_on` entry would be `lint`.
```diff
pipeline:
deploy:
image: debian:stable-slim
commands:
- echo deploying
+depends_on:
+ - lint
+ - build
+ - test
```
Pipelines that need to run even on failures should set the `runs_on` tag.
```diff
pipeline:
notify:
image: debian:stable-slim
commands:
- echo notifying
depends_on:
- deploy
+runs_on: [ success, failure ]
```
Some pipelines don't need the source code, set the `skip_clone` tag to skip cloning:
```diff
pipeline:
notify:
image: debian:stable-slim
commands:
- echo notifying
depends_on:
- deploy
runs_on: [ success, failure ]
+skip_clone: true
```
