Caching downloads

uniget no longer caches downloaded tools. Container image layers are pulled directly from the registry on every install, inspect and self-upgrade. There is no configuration for caching anymore.

Deprecated options

For backwards compatibility, the legacy options are still accepted but they no longer have any effect:

  • Environment variables: UNIGET_CACHE, UNIGET_CACHEDIRECTORY, UNIGET_CACHERETENTION
  • CLI flags: --cache, --cache-directory, --cache-retention

When one of --cache file, --cache docker or --cache containerd is used, uniget prints a warning and proceeds without caching:

$ uniget --cache file install TOOL
WARNING  Cache backend file is no longer supported, pulling images without caching

Any other value for --cache still causes an error. The file/docker/containerd backends have been removed together with the tool-layer download cache.

The subcommands uniget cache info|stats|list|prune remain for backwards compatibility but do nothing.
