How to set multiple commands in one yaml file with Kubernetes? - Stack Overflow

My preference is to multiline the args, this is simplest and easiest to read. Also, the script can be changed without affecting the image, just need to restart the pod. For example, for a mysql dump, the container spec could be something like this:

containers:    - name: mysqldump      image: mysql      command: ["/bin/sh", "-c"]      args:        - echo starting;          ls -la /backups;          mysqldump --host=... -r /backups/file.sql db_name;          ls -la /backups;          echo done;      volumeMounts:        - ...  

The reason this works is that yaml actually concatenates all the lines after the "-" into one, and sh runs one long string "echo starting; ls... ; echo done;".
