Usage:
  cache warmer [flags]

Flags:
      --build-arg multi-arg type                  This flag should be used in conjunction with the dockerfile flag for scenarios where dynamic replacement of the base image is required.
  -c, --cache-dir string                          Directory of the cache. (default "/cache")
      --cache-ttl duration                        Cache timeout in hours. Defaults to two weeks. (default 336h0m0s)
      --customPlatform string                     Specify the build platform if different from the current host
  -d, --dockerfile string                         Path to the dockerfile to be cached. The kaniko warmer will parse and write out each stage's base image layers to the cache-dir. Using the same dockerfile path as what you plan to build in the kaniko executor is the expected usage.
  -f, --force                                     Force cache overwriting.
  -h, --help                                      help for cache
  -i, --image multi-arg type                      Image to cache. Set it repeatedly for multiple images.
      --insecure-pull                             Pull from insecure registry using plain HTTP
      --insecure-registry multi-arg type          Insecure registry using plain HTTP to pull. Set it repeatedly for multiple registries.
      --log-format string                         Log format (text, color, json) (default "color")
      --log-timestamp                             Timestamp in log output
      --registry-certificate key-value-arg type   Use the provided certificate for TLS communication with the given registry. Expected format is 'my.registry.url=/path/to/the/server/certificate'.
      --registry-client-cert key-value-arg type   Use the provided client certificate for mutual TLS (mTLS) communication with the given registry. Expected format is 'my.registry.url=/path/to/client/cert,/path/to/client/key'.
      --registry-map key-multi-value-arg type     Registry map of mirror to use as pull-through cache instead. Expected format is 'orignal.registry=new.registry;other-original.registry=other-remap.registry'
      --registry-mirror multi-arg type            Registry mirror to use as pull-through cache instead of docker.io. Set it repeatedly for multiple mirrors.
      --skip-default-registry-fallback            If an image is not found on any mirrors (defined with registry-mirror) do not fallback to the default registry. If registry-mirror is not defined, this flag is ignored.
      --skip-tls-verify-pull                      Pull from insecure registry ignoring TLS verify
      --skip-tls-verify-registry multi-arg type   Insecure registry ignoring TLS verify to pull. Set it repeatedly for multiple registries.
  -v, --verbosity string                          Log level (trace, debug, info, warn, error, fatal, panic) (default "info")
