Hi Tom,

I have a question about the yaml below:

options:
  k3s:
    extraArgs:
      - arg: --no-deploy=traefik
        nodeFilters:
          - server:*
      - arg: --kube-apiserver-arg=feature-gates=HPAContainerMetrics=true
        nodeFilters:
          - server:*

I want to add a third -arg, but I am lost, could you be of assistance? Thanks

[Evantage-WS]

Anybody? I need this urgently, thanks

[TomWright]

An easy way is using the put document command: https://dasel.tomwright.me/s/c8557111-a4af-4462-9474-d92659e8ae88

cat x.yaml | dasel put document -p yaml -d json '.options.k3s.extraArgs.[]' '{"arg": "--x", "a": "b"}'

[Evantage-WS]

Thanks, but this is not the complete solution to my problem, I especially have a problem getting the "nodeFilters:" and on the next line "-server:*" to work.

- arg: --kube-apiserver-arg=feature-gates=HPAContainerMetrics=true
  nodeFilters:
    - server:*

Could you give it a try? Thanks again

[Evantage-WS]

Could you please also give an example how to delete this entry? I am struggeling with the '--'.

- arg: --no-deploy=traefik
  nodeFilters:
   - server:*

Thanks

Any help?

[TomWright]

Could I get the full input file and expected output please?

Hi,

This is the input:

options:
  k3s:
    extraArgs:
      - arg: --no-deploy=traefik
        nodeFilters:
          - server:*
      - arg: --kube-apiserver-arg=feature-gates=HPAContainerMetrics=true
        nodeFilters:
          - server:*

and I need to delete a part, resulting in:

options:
  k3s:
    extraArgs:
      - arg: --kube-apiserver-arg=feature-gates=HPAContainerMetrics=true
        nodeFilters:
          - server:*

[TomWright]

Thanks for that. Looks like I need to update the selector parsing slightly - the 2nd = character is messing with it. I'll work on this and update you soon

[Evantage-WS]

Great, thanks, I wait for your message

[TomWright]

Hey @Evantage-WS,

As of v1.27.1 the following should work for you:

dasel delete -f in.yaml -o - '.options.k3s.extraArgs.(arg=--no-deploy=traefik)'

If you don't want to wait for the homebrew PR's to go through then you can install the development version.

It is working, thanks
