Volume Cache
This plugin requires Volume configuration. This means your repository Trusted flag must be enabled. This should not be enabled in untrusted environments.
The volume cache plugin can be used to preserve files and directories between builds. The below pipeline configuration demonstrates simple usage.
kind: pipeline
name: default
steps:
- name: restore-cache
image: drillster/drone-volume-cache
volumes:
- name: cache
path: /cache
settings:
restore: true
mount:
- ./node_modules
- name: rebuild-cache
image: drillster/drone-volume-cache
volumes:
- name: cache
path: /cache
settings:
rebuild: true
mount:
- ./node_modules
volumes:
- name: cache
host:
path: /tmp/cache
The mount attribute defines a list of files or directories that should be cached and restored.
The cached files or directories must be located in your build workspace. It is not possible to cache files outside of your build workspace.
- name: restore-cache
image: drillster/drone-volume-cache
volumes:
- name: cache
path: /cache
settings:
restore: true
+ mount:
+ - ./node_modules
The rebuild
flag instructs the plugin to copy files from the build environment to the host machine. This should be declared at the end of your pipeline.
- name: rebuild-cache
image: drillster/drone-volume-cache
volumes:
- name: cache
path: /cache
settings:
+ rebuild: true
mount:
- ./node_modules
The restore
flag instructs the plugin to copy files from the host machine to your build environment. This should be declared at the beginning of your pipeline, before your build steps.
- name: restore-cache
image: drillster/drone-volume-cache
volumes:
- name: cache
path: /cache
settings:
+ restore: true
mount:
- ./node_modules
The volume attribute defines the path on the host machine where the cache is stored. The host machine volume must be mounted into container path /cache
.
- name: restore-cache
image: drillster/drone-volume-cache
+ volumes:
+ - name: cache
path: /cache
settings:
restore: true
mount:
- ./node_modules

Additional Functionality
The volume cache plugin reacts to special directives in a commit message to provide additional functionality. Include one of the following directives somewhere in your commit message to trigger their respective actions:
- [CLEAR CACHE]
- instruct the plugin to clear the entire cache. This only influences the restoring step, the plugin will still rebuild cache if instructed to do so.
- [NO CACHE]
- instruct the plugin not to restore or rebuild cache for this build.
