layer-container-runtime-common

This is a library layer for common functions that exist across the container runtimes.

Configuration

Custom Registry CA

If the container runtime needs to pull images from an external registry with self-signed TLS certificates, you will need to configure the runtime with the CA used to sign those certs:

juju config containerd custom-registry-ca=$(base64 /path/to/ca.crt)

Note: this is not required when following the Private Docker Registry documentation, as the docker-registry charm is related to the same certificate provider as the rest of the Charmed Kubernetes cluster.

Tests

Run tox in the root directory for this layer:

tox
