Rally - On-premises: Resolving VM/Docker swarm IP mismatch


Article ID: 139821

CA Agile Central On Premise (Rally)


When the IP address of a VM has changed, sometimes the Docker swarm IP address does not update to match.  This can cause some problems with Docker swarm certificate rotation and thereby a failure of the Docker swarm to start up.  The swarm IP should match the IP address that is assigned to the VM.


The Docker swarm IP can be verified in two ways; via the Cluster link in the on-premise dashboard or command line using a docker command.


To verify the swarm IP via the dashboard

Log into the dashboard using the following address: https://<IP_Address>:8800/dashboard

Click Cluster in the top navigation menu.  The IP address in the Image column should match the IP assigned to the VM



To verify via the command line

SSH into the services appliance as the ops user

Run the following command:

$ docker service ls

The IP addresses highlighted above should match the IP address assigned to the VM



Release : 2.0, 2.01



If the swarm IP addresses do not match the VM's IP address, there are a couple of solutions

There are bootup scripts that try to align the swarm IP address with the VM IP address.  Because of this, a reboot should first be attempted, particularly if the IP address was just changed.

If a reboot does not resolve this issue, then a command can be manually run to update

$ docker service update replicated_replicated-operator --image "<New_IP_Address>:9874/replicated/replicated-operator:stable-2.32.1"



$ docker service update replicated_replicated-operator --image "<HOST_IP_ADDRESS>:9874/replicated/replicated-operator:stable-2.32.1"


Sample output:

image <HOST_IP_ADDRESS>:9874/replicated/replicated-operator:stable-2.32.1 could not be accessed on a registry to record
its digest. Each node will access <HOST_IP_ADDRESS>:9874/replicated/replicated-operator:stable-2.32.1 independently,
possibly leading to different nodes running different
versions of the image.
