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.

1. Specify environment variables for container components

   Specify environment variables for a container components

   devfile.yaml

   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

   Specify environment variables for plugin components

   devfile.yaml

   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)
   

   Note!

   • 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.
