Since few weeks , i try to move my rancher UI - Single Container (non-HA) (1.16.10) to an other host.
all methods i can try failed :
- copy database , the container on new host close with no error …
- copy /var/lib/mysql on new host and mount at volume : container start and shutdown with no error … just exit 0
- try with external database : cant connect to external database
"Cannot create JDBC driver of class ‘’ for connect URL ‘null’"
after start manually mysql service and load dump , i restart the containter and my result is :
[..] org.mariadb.jdbc.internal.util.dao.QueryException: Table 'region' already exists[..]
why? it’s must be like a just a reboot on the same version of rancher …
really need an export/import environment functionality…
