# Welcome to Woodpecker
|
|
|
|
Woodpecker is a simple CI engine with great extensibility. It focuses on executing pipelines inside [containers](https://opencontainers.org/).
|
|
If you are already using containers in your daily workflow, you'll for sure love Woodpecker.
|
|
|
|
|
|
|
|
## .woodpecker.yml
|
|
|
|
- Place your pipeline in a file named `.woodpecker.yml` in your repository
|
|
- Pipeline steps can be named as you like
|
|
- Run any command in the commands section
|
|
|
|
```yaml
|
|
# .woodpecker.yml
|
|
steps:
|
|
build:
|
|
image: debian
|
|
commands:
|
|
- echo "This is the build step"
|
|
a-test-step:
|
|
image: debian
|
|
commands:
|
|
- echo "Testing.."
|
|
```
|
|
|
|
### Steps are containers
|
|
|
|
- Define any container image as context
|
|
- either use your own and install the needed tools in a custom image
|
|
- or search for available images that are already tailored for your needs in image registries like [Docker Hub](https://hub.docker.com/search?type=image)
|
|
- List the commands that should be executed in the container
|
|
|
|
```diff
|
|
steps:
|
|
build:
|
|
- image: debian
|
|
+ image: mycompany/image-with-awscli
|
|
commands:
|
|
- aws help
|
|
```
|
|
|
|
### File changes are incremental
|
|
|
|
- Woodpecker clones the source code in the beginning
|
|
- File changes are persisted throughout individual steps as the same volume is being mounted in all steps
|
|
|
|
```yaml
|
|
# .woodpecker.yml
|
|
steps:
|
|
build:
|
|
image: debian
|
|
commands:
|
|
- touch myfile
|
|
a-test-step:
|
|
image: debian
|
|
commands:
|
|
- cat myfile
|
|
```
|
|
|
|
## Plugins are straightforward
|
|
|
|
- If you copy the same shell script from project to project
|
|
- Pack it into a plugin instead
|
|
- And make the yaml declarative
|
|
- Plugins are Docker images with your script as an entrypoint
|
|
|
|
```Dockerfile
|
|
# Dockerfile
|
|
FROM laszlocloud/kubectl
|
|
COPY deploy /usr/local/deploy
|
|
ENTRYPOINT ["/usr/local/deploy"]
|
|
```
|
|
|
|
```bash
|
|
# deploy
|
|
kubectl apply -f $PLUGIN_TEMPLATE
|
|
```
|
|
|
|
```yaml
|
|
# .woodpecker.yml
|
|
steps:
|
|
deploy-to-k8s:
|
|
image: laszlocloud/my-k8s-plugin
|
|
settings:
|
|
template: config/k8s/service.yml
|
|
```
|
|
|
