/bin/sh kd-JSON file config

[hoycdanny]

Hi Team, How can I adjust the kd-JSON file config, if my Image does not have bash but only sh?

Error Message OCI runtime exec failed: exec failed: container_linux.go:349: starting container process caused "exec: \"/bin/bash\": stat /bin/bash: no such file or directory": unknown

Hmm. bash is a requirement at the moment. I'm not sure though if any of the current shell executions rely on bash features, so we may be able to change that.

[hoycdanny]

But some light images only provide /bin/sh, for example apache https and busybody.

[joel-bluedata]

Yup very true. I think I'm not clear on why you would need/want to use KubeDirector for those particular examples, but I can easily imagine there being other cases where bash would not be available.

[hoycdanny]

Because I hope that customers can deploy the service through HPECP kd dashboard one click, our current deployment service dashboard through kubectl YAML is not friendly.

[joel-bluedata]

I'm back from leave; will take this up. Note to self... the wiki currently (now) lists bash as an image requirement, so I would need to revert that if we use sh instead.

[joel-bluedata]

Moving stuff not related to API deprecation into 0.11.0.

We'll get this one in 0.11.0 for sure!

[joel-bluedata]

To avoid making this a backward-incompatible change, probably there would be a kdapp field to optionally specify the shell used, defaulting to bash.
