[feature] investigating applicability of ytt about aviator HOT 4 CLOSED

Hi @aegershman

very interesting. I talked to @nimakaviani recently about adding ytt support. I'm already investigating if I can integrate it somehow. I'll leave this issue open for ideas.

Thx very much for open this issue.

I played a little bit with ytt and I think it can be nicely integrated with Aviator. Still need to take a look at the code. The idea I have so far is to have ytt separated from the spruce config in the aviator.yml with the following concept:

• template (ytt)
• merge (spruce)
• modify (goml)
• squash (aviator)
• execute (fly|kubectl|others)

For executors I think I create a plug-in point and let them be added separately to Aviator. Something like aviator install ansible-executor.

Moreover, I thinking about to change the aviator yaml such that the order of the processes like template, merge, modify, squash can be defined by the user. Today, the order is strict: spruce->squash->execute

@aegershman off topic, but you may want to connect with @cdutra since he was playing around with ytt and concourse pipelines as well. yall might have some interesting things to share.

@herrjulz Would you mind summarizing your thoughts / findings? Is ytt planned to be supported?
