环境变量

Woodpecker 提供将环境变量传递给各个管道步骤的功能。请注意，这些变量无法覆盖任何现有的内置变量。带有自定义环境变量的示例管道步骤：

 steps:
   - name: build
     image: golang
+    environment:
+      CGO: 0
+      GOOS: linux
+      GOARCH: amd64
     commands:
       - go build
       - go test

请注意，环境部分无法扩展环境变量。如果您需要扩展变量，应该在命令部分导出它们。

 steps:
   - name: build
     image: golang
-    environment:
-      - PATH=$PATH:/go
     commands:
+      - export PATH=$PATH:/go
       - go build
       - go test

注意

${variable} 表达式会进行预处理。如果您不想让预处理器评估您的表达式，必须转义：

 steps:
   - name: build
     image: golang
     commands:
-      - export PATH=${PATH}:/go
+      - export PATH=$${PATH}:/go
       - go build
       - go test

内置环境变量

这是您的管道容器可用的所有环境变量的参考列表。这些变量在运行时注入到您的管道步骤和插件容器中。

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.

WOODPECKER_ENVIRONMENT=first_var:value1,second_var:value2

These can be used, for example, to manage the image tag used by multiple projects.

WOODPECKER_ENVIRONMENT=GOLANG_VERSION:1.18

 steps:
   - name: build
-    image: golang:1.18
+    image: golang:${GOLANG_VERSION}
     commands:
       - [...]

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:

 steps:
   - name: s3
     image: woodpeckerci/plugin-s3
     settings:
+      target: /target/${CI_COMMIT_SHA}

Example tag substitution:

 steps:
   - name: s3
     image: woodpeckerci/plugin-s3
     settings:
+      target: /target/${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:

 steps:
   - name: s3
     image: woodpeckerci/plugin-s3
     settings:
+      target: /target/${CI_COMMIT_SHA:0:8}

Example variable substitution strips v prefix from v.1.0.0:

 steps:
   - name: s3
     image: woodpeckerci/plugin-s3
     settings:
+      target: /target/${CI_COMMIT_TAG##v}
