feature: dump current config

[byteplow]

tasks

• dump the rendered template

• dump all config files

• dump secrets? only metadata? encrypted?

• replace services.service.image in dump with the image sha

  • the image name should stay the same, the tag should be replaced with the sha
  • add the tag as comment in case the specific version is deleted

• apply from dump

why?

To be able to backup the running stack.
The dump should work, if:

• the chart/version is no longer available
• values have changed or are not available.
• the there is a new image version with the used tag (e.g. latest was used). The new version may no be compatible any more.
