Filter the path based in search

[junaid18183]

Not sure whether what I am asking is supported or not but in all my searches to documentation yield nothing, that's why I am not adding feature_requst

here is my input yaml file

profile: default
hub: ghcr.io/junaid18183/istio
tag: 1.11.3
domain: ijuned.com
revision: ""
openshift: false
imagePullSecrets: []
monitoring:
  enabled: false
postInstallHook:
  image: ghcr.io/junaid18183/base:8.4
  name: base
cni:
  image:
    hub: ghcr.io/junaid18183/istio

All I want is the find and replace the ghcr.io/junaid18183/ to docker.io/junaid18183/ and create the patch file as ( containing keys containing only the search items

hub: docker.io/junaid18183/istio
postInstallHook:
  image: docker.io/junaid18183/base:8.4
cni:
  image:
    hub: docker.io/junaid18183/istio

And the structure and key's to find the string is dynamic.

I tried

yq '... | select( .== "*ghcr.io/junaid18183*") = "docker.io/junaid18183" | .[]' /tmp/1.yaml
yq ' {} as $o | (.. | select(. == "*jun*")) as $t |(($t | path | .[]) as $p ireduce($o; .[$p]))=$t  | $o' /tmp/1.yaml

Had to think about this one - and I realised that to do it - you need a setpath operator like jq - which yq doesn't yet have. I will add it to the next release, then you will be able to:

yq '(.. | select(tag == "!!str" and test("ghcr.io/junaid18183"))) as $i ireduce({}; setpath($i | path; $i | sub("ghcr.io", "docker.io"))) file.yaml

Explanation:

1. Find all the entries you wish to update (.. | select(tag == "!!str" and test("ghcr.io/junaid18183"))
2. Use reduce to create a new object, which will only contain these entries
3. Create entries in the new object, using the paths of the found entries setpath($i | path ; ...
4. For the value param of setpath, substitute the old value with the new value

You won't be able to do this until I release a new version (4.28+)

Thanks for the prompt reply, I had to hack using bash till then, Below is the hack if some on stumbles upon it

INPUT_FILE=/tmp/source.yaml
DEST_FILE=/tmp/dest.yaml

DEST_REGISTRY="docker.io/junaid18183"
SOURCE_REGISTRY="ghcr.io/junaid18183"
#------------------------------------------------------------
yq -o=props '... comments = ""' $INPUT_FILE | grep -E "$SOURCE_REGISTRY" | yq -p=props >$DEST_FILE
images=($(yq -o=props '... comments = ""' $DEST_FILE | grep -E "$SOURCE_REGISTRY" | awk '{print $3}'))
keys=($(yq -o=props '... comments = ""' $DEST_FILE | grep -E "$SOURCE_REGISTRY" | awk '{print $1}'))

count=0
cmd=""
for i in ${keys[@]}; do
    if [ -n "${cmd}" ]; then
        cmd="$cmd | "
    fi
    image=${images[$count]}
    new_image=${image/$SOURCE_REGISTRY/$DEST_REGISTRY}

    cmd=$cmd".$i = \"${new_image}\" " \
        count=$count+1
done

cmd="yq -i '$cmd' $DEST_FILE"
eval $cmd
echo "$DEST_FILE"

FYI 4.28.1 has been released :)

oh wow, thanks for the swift reply , confirmed its working as expected

❯ yq '(.. | select(tag == "!!str" and test("ghcr.io/junaid18183"))) as $i ireduce({}; setpath($i | path; $i | sub("ghcr.io", "docker.io")))' /tmp/source.yaml
