I love it!

Any reason not using ‘sort -u’?

perryao commented 5 years ago

Hi @kmluoh. I actually wasn't aware that sort had a -u flag to provide unique results. Works great. I'll update this post to simplify to that. Thanks!

You are welcome. Good to know it helps.

I got error "docker tag" requires exactly 2 arguments,

maybe miss &&

before fix

xargs -I % -n 1 -P 4 bash -c "docker pull % && docker tag % my.registry.com/% docker push my.registry.com/%"

after fix

xargs -I % -n 1 -P 4 bash -c "docker pull % && docker tag % my.registry.com/% && docker push my.registry.com/%"

some image cannot push，got error invalid reference format, I didn't find the reason.

I split the script into 3 parts and it was executed successfully.

# docker pull image
helm template sentry-8.1.0.tgz | yq '..|.image? | select(.)' \
| sort \
| uniq \
| xargs -I % -n 1 -P 4 bash -c "docker pull %"

# retag
helm template sentry-8.1.0.tgz | yq '..|.image? | select(.)' \
| sort \
| uniq \
| xargs -I % -n 1 -P 4 bash -c "docker tag % my.registry.com/%"

# docker push image
helm template sentry-8.1.0.tgz | yq '..|.image? | select(.)' \
| sort \
| uniq \
| xargs -I % -n 1 -P 4 bash -c "docker push my.registry.com/%"

my image list

$ helm template sentry-8.1.0.tgz | yq '..|.image? | select(.)' \
| sort \
| uniq \
| xargs -I % -n 1 -P 4 bash -c "echo %"

Thanks for the write up. I had to make the following change to the yq command on centos8 adding an e before the yq arguments and ending it with a -. It looks like its trying to parse that last argument as a file on centos.

helm template . |  yq e '..|.image? | select(.)' -
