CRC provides a config option called bundle to configure the location of the bundle. This option is useful when you want to use a bundle that is not the default one or user want to try a bundle which is not part of release but available at the OpenShift mirror location. The bundle option can accept local filesystem paths, container registry URLs, and http/https URLs. This blog post will guide you through the process of using the bundle option using config or setup/start commands.

Using bundle option with crc config command

You can use the crc config set bundle command to set the bundle location. This command can accept local filesystem paths, container registry URLs, and http/https URLs. Here are some examples:

# Assume user want to use microshift-4.15.0 bundle which is not part of crc release but available at the OpenShift mirror location
crc config set bundle https://developers.redhat.com/content-gateway/file/pub/openshift-v4/clients/crc/bundles/microshift/4.15.0/crc_microshift_libvirt_4.15.0_amd64.crcbundle
crc setup
crc start

Using bundle option with crc setup and crc start commands

crc setup --bundle https://developers.redhat.com/content-gateway/file/pub/openshift-v4/clients/crc/bundles/microshift/4.15.0/crc_microshift_libvirt_4.15.0_amd64.crcbundle
crc start --bundle https://developers.redhat.com/content-gateway/file/pub/openshift-v4/clients/crc/bundles/microshift/4.15.0/crc_microshift_libvirt_4.15.0_amd64.crcbundle

Beware, if you use -b https:// there will be no signature checks Bundles downloaded from mirror.openshift.com can be verified this way:

curl -L -O https://developers.redhat.com/content-gateway/file/pub/openshift-v4/clients/crc/bundles/microshift/4.15.0/crc_microshift_libvirt_4.15.0_amd64.crcbundle
curl -L -O https://developers.redhat.com/content-gateway/file/pub/openshift-v4/clients/crc/bundles/microshift/4.15.0/crc_microshift_libvirt_4.15.0_amd64.crcbundle.sha256
sha256sum crc_microshift_libvirt_4.15.0_amd64.crcbundle => should match with the content of crc_microshift_libvirt_4.15.0_amd64.crcbundle.sha256

Conclusion

This blog post has shown you how to use the bundle option with CRC. By following these steps, you can quickly and easily spin up a local cluster using the bundle of your choice. As usual, we’d like to get your feedback on all this work!
