jq match a regex

Let's say I have a file, I run cat testTab.json | jq '.action.service.spec.task| select(.container) | .container' and it gives me

{
  "image": "ubuntu:latest",
  "args1": "tail",
  "args2": "-f",
  "args3": "/dev/null",
  "mounts": {
    "source": "/home/testVolume",
    "target": "/opt"
  },
  "dns_config": null
}

How should I edit this command the get all args (args1, args2 and args3) values ("tail" "-f" "/dev/null")

Complement your jq pipeline with the following filter:

jq -r 'yourfilter | to_entries 
       | map(select(.key | test("^args[0-9]+")).value) | @tsv' testTab.json

The output:

tail    -f  /dev/null

Though, if you would have posted your initial testTab.json contents - I would help to optimize your current filter.
