# Environment variables
|
|
|
|
Woodpecker provides the ability to pass environment variables to individual pipeline steps. Note that these can't overwrite any existing, built-in variables. Example pipeline step with custom environment variables:
|
|
|
|
```diff
|
|
steps:
|
|
build:
|
|
image: golang
|
|
+ environment:
|
|
+ - CGO=0
|
|
+ - GOOS=linux
|
|
+ - GOARCH=amd64
|
|
commands:
|
|
- go build
|
|
- go test
|
|
```
|
|
|
|
Please note that the environment section is not able to expand environment variables. If you need to expand variables they should be exported in the commands section.
|
|
|
|
```diff
|
|
steps:
|
|
build:
|
|
image: golang
|
|
- environment:
|
|
- - PATH=$PATH:/go
|
|
commands:
|
|
+ - export PATH=$PATH:/go
|
|
- go build
|
|
- go test
|
|
```
|
|
|
|
> Please be warned that `${variable}` expressions are subject to pre-processing. If you do not want the pre-processor to evaluate your expression it must be escaped:
|
|
|
|
```diff
|
|
steps:
|
|
build:
|
|
image: golang
|
|
commands:
|
|
- - export PATH=${PATH}:/go
|
|
+ - export PATH=$${PATH}:/go
|
|
- go build
|
|
- go test
|
|
```
|
|
|
|
## Built-in environment variables
|
|
|
|
This is the reference list of all environment variables available to your pipeline containers. These are injected into your pipeline step and plugins containers, at runtime.

## Global environment variables
|
|
|
|
If you want specific environment variables to be available in all of your pipelines use the `WOODPECKER_ENVIRONMENT` setting on the Woodpecker server. Note that these can't overwrite any existing, built-in variables.
|
|
|
|
```diff
|
|
services:
|
|
woodpecker-server:
|
|
[...]
|
|
environment:
|
|
- [...]
|
|
+ - WOODPECKER_ENVIRONMENT=first_var:value1,second_var:value2
|
|
```
|
|
|
|
These can be used, for example, to manage the image tag used by multiple projects.
|
|
|
|
```diff
|
|
steps:
|
|
build:
|
|
- image: golang:1.18
|
|
+ image: golang:${GOLANG_VERSION}
|
|
commands:
|
|
- [...]
|
|
environment:
|
|
- [...]
|
|
+ - WOODPECKER_ENVIRONMENT=GOLANG_VERSION:1.18
|
|
```
|
|
|
|
## String Substitution
|
|
|
|
Woodpecker provides the ability to substitute environment variables at runtime. This gives us the ability to use dynamic settings, commands and filters in our pipeline configuration.
|
|
|
|
Example commit substitution:
|
|
|
|
```diff
|
|
steps:
|
|
docker:
|
|
image: plugins/docker
|
|
settings:
|
|
+ tags: ${CI_COMMIT_SHA}
|
|
```
|
|
|
|
Example tag substitution:
|
|
|
|
```diff
|
|
steps:
|
|
docker:
|
|
image: plugins/docker
|
|
settings:
|
|
+ tags: ${CI_COMMIT_TAG}
|
|
```
|
|
|
|
## String Operations
|
|
|
|
Woodpecker also emulates bash string operations. This gives us the ability to manipulate the strings prior to substitution. Example use cases might include substring and stripping prefix or suffix values.
|
|
|
|
| OPERATION | DESCRIPTION |
|
|
| ------------------ | ------------------------------------------------ |
|
|
| `${param}` | parameter substitution |
|
|
| `${param,}` | parameter substitution with lowercase first char |
|
|
| `${param,,}` | parameter substitution with lowercase |
|
|
| `${param^}` | parameter substitution with uppercase first char |
|
|
| `${param^^}` | parameter substitution with uppercase |
|
|
| `${param:pos}` | parameter substitution with substring |
|
|
| `${param:pos:len}` | parameter substitution with substring and length |
|
|
| `${param=default}` | parameter substitution with default |
|
|
| `${param##prefix}` | parameter substitution with prefix removal |
|
|
| `${param%%suffix}` | parameter substitution with suffix removal |
|
|
| `${param/old/new}` | parameter substitution with find and replace |
|
|
|
|
Example variable substitution with substring:
|
|
|
|
```diff
|
|
steps:
|
|
docker:
|
|
image: plugins/docker
|
|
settings:
|
|
+ tags: ${CI_COMMIT_SHA:0:8}
|
|
```
|
|
|
|
Example variable substitution strips `v` prefix from `v.1.0.0`:
|
|
|
|
```diff
|
|
steps:
|
|
docker:
|
|
image: plugins/docker
|
|
settings:
|
|
+ tags: ${CI_COMMIT_TAG##v}
|
|
```
