We tried to upgarde our rancher environment from 1.6.18 to 1.6.22.
The steps we did was
.1 stop current
2. download new one
3. restart with new image.
4. logged into GUI
went to GUI looks good but now ALL Infrastructure Stack say unhealthy
I tried to click on “upgrade” them but goes into loop and nothing happens and our “HOSTS” can’t connect.
we are using CentOS 7 with docker “Docker version 18.06.1-ce, build e68fc7a”
I’m new to rancher , what are some troubleshooting tips I can look into ? etc… where might the log files be ?
