Specifying persistent storage

Components of any type can specify the custom volumes to be mounted on specific locations within the image. Note that the volume names are shared across all components and therefore this mechanism can also be used to share file systems between components.

Procedure

1. Specify volumes for container type:

   Specifying volumes for container type

   devfile.yaml

   schemaVersion: 2.0.0
   metadata:
     name: MyDevfile
   components:
     - name: MyDevfile
       container:
         image: golang
         memoryLimit: 512Mi
         mountSources: true
         command: ['sleep', 'infinity']
         volumeMounts:
           - name: cache
             path: /.cache
   

2. Specify volumes for plugin type:

   Specifying volumes for plugin type

   devfile.yaml

   scheamVersion: 2.0.0
   metadata:
     name: MyDevfile
   components:
     - name: theia-editor
       plugin:
         id: eclipse/che-theia/next
         env:
         - name: HOME
           value: $(PROJECTS_ROOT)
         volumeMounts:
         - name: cache
           path: /.cache
   

3. Specify volumes for kubernetes/openshift type:

   Specifying volumes for kubernetes/openshift type

   devfile.yaml

   schemaVersion: 2.0.0
   metadata:
     name: MyDevfile
   components:
     - name: mongo
       openshift:
         reference: mongo-db.yaml
         volumeMounts:
         - name: mongo-persistent-storage
           path: /data/db
