2.5. Using a proxy in the CRI-O container runtime

Procedure

1. Create the directory for the configuration file if it does not exist:

   $ sudo mkdir /etc/systemd/system/crio.service.d/

2. Add the following settings to the /etc/systemd/system/crio.service.d/00-proxy.conf file:

   [Service]
   Environment=NO_PROXY="localhost,127.0.0.1"
   Environment=HTTP_PROXY="http://$PROXY_USER:$PROXY_PASSWORD@$PROXY_SERVER:$PROXY_PORT/"
   Environment=HTTPS_PROXY="http://$PROXY_USER:$PROXY_PASSWORD@$PROXY_SERVER:$PROXY_PORT/"

   重要

   You must define the Service section of the configuration file for the environment variables or the proxy settings fail to apply.

3. Reload the configuration settings:

   $ sudo systemctl daemon-reload

4. Restart the CRI-O service:

   $ sudo systemctl restart crio

5. Restart the MicroShift service to apply the settings:

   $ sudo systemctl restart microshift

Verification

1. Verify that pods are started by running the following command and examining the output:

   $ oc get all -A

2. Verify that MicroShift is able to pull container images by running the following command and examining the output:

   $ sudo crictl images
