Prevent host failure or Ambari inaccessibility during docker upgrade

[#1]

When you do a 'yum update', after you install some new software on one or more nodes on the cluster, it does upgrade the docker container was well. So will this not cause any issues like node failure from cloudbreak shell or CLI?

[#2 · Accepted solution]

The container should not be updated - you mean to say the docker version? Contiamners can be updated with docker pull but you should not be concerned as an end user or operator about this. Did you face some issues or is this an observation?

Its just an observation and was curious about any such case. Thanks for the response!
