Using Container Registries
A Docker registry is a stateless, server-side application. You can use registries in Containers for vRealize
Automation to store and distribute Docker images.
To configure a registry, you need to provide its address, a custom registry name, and optionally
credentials. The address must start with HTTP or HTTPS to designate whether the registry is secured or
unsecured. If the connection type is not provided, HTTPS is used by default.
Note For HTTP you must declare port 80; for HTTPS you must declare port 443. If no port is specified,
the Docker engine expects port 5000, which can result in broken connections.
Note It is recommended you do not use HTTP registries because HTTP is considered insecure. If you
want to use HTTP, you must modify the DOCKER_OPTS property on each host as follows:
DOCKER_OPTS="--insecure-registry myregistrydomain.com:5000".
For more information, see the Docker documentation at https://docs.docker.com/registry/insecure/.
