Find image tag variants of a given tag

Question

If I run this:

$ docker search node

I get some results in the terminal:

NAME                                   DESCRIPTION                                     STARS               OFFICIAL            AUTOMATED

my question is - is there a command I can use to find all the variants of the first result?

I am looking to get a list of all the images/tags like so:

[
   "node:4.2",
   "node:5.1",
   "node:5.3",
   "node:5.45",
   "node:5.7",
   "node:6.2",
   "node:7",
   "node:8",
   "node:9",
   // ...
   "node:10"
]

Docker search doesn't have this feature

What you can do instead is use a simple curl command combine with jq :

https://registry.hub.docker.com/v1/repositories/<NAME>/tags

Example :

curl https://registry.hub.docker.com/v1/repositories/node/tags | jq -r '.[].name'

Will return all the tags :

...
chakracore-8.11
chakracore-8.11.1
chakracore-8.9
chakracore-8.9.4
jessie
onbuild
slim
stretch
wheezy

And If you want to get all tags of all result :

for i in $(docker search --format {{.Name}} node); do
    echo "All tag for image : $i"
    curl https://registry.hub.docker.com/v1/repositories/$i/tags | jq -r '.[].name'
done

Or all tag of the first result :

name=$(docker search --limit 1 --format {{.Name}} node)
curl https://registry.hub.docker.com/v1/repositories/$name/tags | jq -r '.[].name'
