Documented jq version = 1.6, actually used in the Shell-Operator image is 1.5

[Blokje5]

The documentation refers to 1.6 as the version used for jq: https://github.com/flant/shell-operator/blob/master/HOOKS.md#jqfilter. However, running jq --version shows that the latest image is still on 1.5.

> jq --version
jq-1.5-1-a5b5cbe

Preferably the Docker Image uses jq version 1.6.

Hello!

I think you are talking about ubuntu based image? Ubuntu 18.04 still has jq-1.5 in the repository. You can use alpine based image if you need jq-1.6.

Please, consider that jq-1.6 has poor performance. It is not significant for one-time scripts, but hooks can be executed frequently and shell-operator Pod will eat up a lot of cpu. We've faced this problem with addon-operator and found a later commit that fixes the performance issue. See flant/libjq-go#10 and issues in https://github.com/stedolan/jq repository.

It seems that documentation is outdated: shell-operator do not use jq 1.6, it uses a more recent commit, I'll fix it.

Also, can you elaborate more on what new features of jq-1.6 do you need in hooks?

Thanks for the reply! Good to know about the performance problems in 1.6. The main reason I was using 1.6 is because of the walk function. But if I want that behaviour I can just add the walk function as a custom function.
