Chapter 14. Setting up additional trusted certificate authorities for builds
Use the following sections to set up additional certificate authorities (CA) to be trusted by builds when pulling images from an image registry.
The procedure requires a cluster administrator to create a ConfigMap
and add additional CAs as keys in the ConfigMap
.
-
The
ConfigMap
must be created in theopenshift-config
namespace. domain
is the key in theConfigMap
andvalue
is the PEM-encoded certificate.-
Each CA must be associated with a domain. The domain format is
hostname[..port]
.
-
Each CA must be associated with a domain. The domain format is
-
The
ConfigMap
name must be set in theimage.config.openshift.io/cluster
cluster scoped configuration resource’sspec.additionalTrustedCA
field.
14.1. Adding certificate authorities to the cluster 링크 복사링크가 클립보드에 복사되었습니다!
You can add certificate authorities (CA) to the cluster for use when pushing and pulling images with the following procedure.
Prerequisites
-
You must have access to the public certificates of the registry, usually a
hostname/ca.crt
file located in the/etc/docker/certs.d/
directory.
Procedure
Create a
ConfigMap
in theopenshift-config
namespace containing the trusted certificates for the registries that use self-signed certificates. For each CA file, ensure the key in theConfigMap
is the hostname of the registry in thehostname[..port]
format:oc create configmap registry-cas -n openshift-config \ --from-file=myregistry.corp.com..5000=/etc/docker/certs.d/myregistry.corp.com:5000/ca.crt \ --from-file=otherregistry.com=/etc/docker/certs.d/otherregistry.com/ca.crt
$ oc create configmap registry-cas -n openshift-config \ --from-file=myregistry.corp.com..5000=/etc/docker/certs.d/myregistry.corp.com:5000/ca.crt \ --from-file=otherregistry.com=/etc/docker/certs.d/otherregistry.com/ca.crt
