NAME
containers-certs.d - Directory for storing custom container-registry TLS configurations
DESCRIPTION
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).
Directory Structure
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
