# NAME
|
|
registries.conf - Syntax of System Registry Configuration File
|
|
|
|
# DESCRIPTION
|
|
The REGISTRIES configuration file is a system-wide configuration file for container image
|
|
registries. The file format is TOML.
|
|
|
|
# FORMAT
|
|
The TOML_format is used to build simple list format for registries under two
|
|
categories: `search` and `insecure`. You can list multiple registries using
|
|
as a comma separated list.
|
|
|
|
Search registries are used when the caller of a container runtime does not fully specify the
|
|
container image that they want to execute. These registries are prepended onto the front
|
|
of the specified container image until the named image is found at a registry.
|
|
|
|
Insecure Registries. By default container runtimes use TLS when retrieving images
|
|
from a registry. If the registry is not setup with TLS, then the container runtime
|
|
will fail to pull images from the registry. If you add the registry to the list of
|
|
insecure registries then the container runtime will attempt use standard web protocols to
|
|
pull the image. It also allows you to pull from a registry with self-signed certificates.
|
|
Note insecure registries can be used for any registry, not just the
|
|
registries listed under search.
|
|
|
|
The following example configuration defines two searchable registries and one
|
|
insecure registry.
|
|
|
|
```
|
|
[registries.search]
|
|
registries = ["registry1.com", "registry2.com"]
|
|
|
|
[registries.insecure]
|
|
registries = ["registry3.com"]
|
|
```
