8.4. Configuring the dynamic plugins cache

You can set the following optional dynamic plugin cache parameters in your dynamic-plugins.yaml file:

forceDownload: Set the value to true to force a reinstall of the plugin, bypassing the cache. The default value is false.
pullPolicy: Similar to the forceDownload parameter and is consistent with other image container platforms. You can use one of the following values for this key:
- Always: This value compares the image digest in the remote registry and downloads the artifact if it has changed, even if the plugin was previously downloaded.
- IfNotPresent: This value downloads the artifact if it is not already present in the dynamic-plugins-root folder, without checking image digests.
  注意
  The pullPolicy setting is also applied to the NPM downloading method, although Always will download the remote artifact without a digest check. The existing forceDownload option remains functional, however, the pullPolicy option takes precedence. The forceDownload option may be deprecated in a future Developer Hub release.

Example dynamic-plugins.yaml file configuration to download the remote artifact without a digest check:

plugins:
  - disabled: false
    pullPolicy: Always
