Defining environment variables

Environment variables are supported by the following component types: container, plugin, kubernetes, openshift. If the component has multiple containers, environment variables will be provisioned for each container.

Procedure

  1. Specify environment variables for container components

    Example 1. Specify environment variables for a container components
    schemaVersion: 2.0.0
metadata:
  name: MyDevfile
components:
  - name: go
    container:
      image: golang
      memoryLimit: 512Mi
      mountSources: true
      command: ['sleep', 'infinity']
      env:
        - name: GOPATH
          value: $(PROJECTS_ROOT)/go

  2. Specify environment variables for plugin components

    Example 2. Specify environment variables for a plugin component
    schemaVersion: 2.0.0
metadata:
  name: MyDevfile
  - name: theia-editor
    plugin:
      id: eclipse/che-theia/next
      memoryLimit: 2Gi
      env:
      - name: HOME
        value: $(CHE_PROJECTS_ROOT)

  • The variable expansion works between the environment variables, and it uses the Kubernetes convention for the variable references.

  • The predefined variables are available for use in custom definitions.
