containers-certs.d - Directory for storing custom container-registry TLS configurations

A custom TLS configuration for a container registry can be configured by creating a directory under $HOME/.config/containers/certs.d or /etc/containers/certs.d. The name of the directory must correspond to the host:port of the registry (e.g., my-registry.com:5000).

A certs directory can contain one or more files with the following extensions: • *.crt files with this extensions will be interpreted as CA certificates • *.cert files with this extensions will be interpreted as client certificates • *.key files with this extensions will be interpreted as client keys Note that the client certificate-key pair will be selected by the file name (e.g., client.{cert,key}). An exemplary setup for a registry running at my-registry.com:5000 may look as follows: /etc/containers/certs.d/ <- Certificate directory └── my-registry.com:5000 <- Hostname:port ├── client.cert <- Client certificate ├── client.key <- Client key └── ca.crt <- Certificate authority that signed the registry certificate
