Hi, i’m new. sorry by this stupid question: ¿what does “Started-Once” status mean?
Hello, welcome!
Some containers are initialization containers or volume containers, and do not have any services to actually run, so they will start once, create their volumes and then exit. Then another container can use that container and it’s volumes.
An example might be a MySQL service where one container would start once, creating the MySQL database and initialize it with some data, and then terminate.
Another container starts after that, using volumes_from:, and uses the initialized database. This lets the first container have only initialization logic, and the second container only needs to have mysql daemon logic.
The first container started will say “Started-Once” which says, I successfully did my initialization and have now quit.
Hope this helps.
