Munging JSON with JQ - without using grep and awk

Further to a previous post: -

Grep AND awk

I wanted to achieve much the same, but only using jq

So here we go: -

ic is images --output JSON | jq -r '.[] | {Name:.name,Architecture:.operating_system.architecture,Status:.status} | select((.Name | contains("ubuntu")) and (.Architecture | startswith("s390x")) and (.Status | startswith("available")))'

which returns: -

{
  "Name": "ibm-ubuntu-18-04-1-minimal-s390x-3",
  "Architecture": "s390x",
  "Status": "available"
}

as opposed to the alternative: -

ic is images | awk '/s390x/ && /ubuntu/ && /available/'
