After reboot SolusIO Master interface is not available: failed to create endpoint gateway_ingress-sbox on network docker_gwbridge

Symptoms

• After reboot, SolusIO Master interface is not available - the following error can be found in the system journal on SolusIO Master node:

  # journalctl -u docker | grep gateway_ingress
  dockerd[564826]: level=error msg="fatal task error" error="container ingress-sbox: endpoint create on GW Network failed: failed to create endpoint gateway_ingress-sbox on network docker_gwbridge

• Interface docker_gwbridge is not located in docker zone in firewalld:

  # firewall-cmd --get-active-zones
  docker
  interfaces: docker0
  trusted
  interfaces: docker_gwbridge

Cause

The issue is confirmed as a bug with ID SIO-2857, which was fixed in SolusIO update 1.1.16561.

Resolution

1. Acces SolusIO master node over SSH.

2. Remove interface docker_gwbridge from trusted zone and add it to docker zone:

   # firewall-cmd --permanent --zone=trusted --remove-interface=docker_gwbridge
   # firewall-cmd --permanent --zone=docker --add-interface=docker_gwbridge

3. Restart firewalld:

   # systemctl restart firewalld

4. Recreate SolusIO stack and docker interfaces:

   # docker stack rm solus
   # systemctl restart docker
   # docker stack deploy --with-registry-auth -c /usr/local/solus/config/stack.yml solus
