Deploying MicroShift behind Proxy

When deploying MicroShift behind a proxy, configure the host OS to use the proxy for both yum and CRI-O.

Configuring HTTP(S) proxy for yum

To configure yum to use a proxy, add the following to /etc/yum.conf:

proxy=http://$PROXY_SERVER:$PROXY_SERVER
proxy_username=$PROXY_USER
proxy_password=$PROXY_PASSWORD

Configuring HTTP(S) proxy for CRI-O or Podman

CRI-O and Podman are Go programs that use the built-in net/http package. To use an HTTP(S) proxy you need to set the HTTP_PROXY and HTTPS_PROXY environment variables and optionally the NO_PROXY variable to exclude a list of hosts from being proxied). For example, add the following to /etc/systemd/system/crio.service.d/00-proxy.conf:

[Service]
Environment=NO_PROXY="localhost,127.0.0.1,10.42.0.0/16,10.43.0.0/16"
Environment=HTTP_PROXY="http://$PROXY_USER:$PROXY_PASSWORD@$PROXY_SERVER:$PROXY_PORT/"
Environment=HTTPS_PROXY="http://$PROXY_USER:$PROXY_PASSWORD@$PROXY_SERVER:$PROXY_PORT/"

Restart CRI-O:

sudo systemctl restart crio
