We are current using docker 1.10.3 for our non prod servers, and various DevOps tools.The version is almost 3.5 years old now, and we are missing out on orchestration capabilities and other new features.
Can we check if its possible to upgrade to latest docker community engine (19.03.1), and have following queries in this regard:
- We are using docker across 10+ VMs, where one VM is swarm leader and other are nodes.
- If this upgrade is possible, will our existing containers be compatible with new docker
- If we continue to use docker swarm, does this only provide a CLI or it also provides some web interface / UI to manage nodes?
