How to get Image ID of docker in jenkins?

Question

I need to run docker container through Jenkins. For that I used "Start/Stop Docker Containers" as build step

Start/Stop Docker Containers

Action to choose        : Run container
Docker Cloud name       : docker_demo
ID                      : DOCKER_IMAGE_ID
DNS     
Port bindings           :port
Bind all declared ports :   
Hostname                : ip address

While running the job,it is telling that "Invalid ID". Can anyone suggest,How to get Image ID of docker in jenkins??

Isn't it just the image name like ubuntu:latest? – Gynarchy

Nope.Actually i created one image(which is created while execution time of jenknis job) using docker.repositry(local).Now I need to retrieve that image ID.So how to retrieve it?? – Highclass

Have you solved this problem yet? It seems from the question you may be confused about the difference between a container and an image. – Antler

Answer 1

One liner based on docker documentation:

sudo docker images --filter=reference=image_name --format "{{.ID}}"

Replace image_name by your actual docker image name. You can store that value in a shell variable for further referencing with:

IMAGE_ID=$(sudo docker images --filter=reference=image_name --format "{{.ID}}")

And then access it with $IMAGE_ID

don't forget to close parenthesis at the end: IMAGE_ID=$(docker images --filter=reference=image_name --format "{{.ID}}") – Teerell

Thanks for the heads-up @Tabaraei, I fixed it. – Gora

Answer 2

A simpler way to solve it:

docker images --filter="reference=your_image_name" --quiet

What this command means:

• --filter : Search a image based on name (represented by your_image_name)
• --quiet : Return only the image ID

Reference: https://docs.docker.com/engine/reference/commandline/images/

--no-trunc is also needed here – Devolution

Answer 3

You can see the docker image id (for the images you have built or pulled from docker hub) using the following command: docker images

Update after comments from OP:

docker images --filter only implements dangling=true so you can't search for container ids using this way. so you'll have to rely on shell scripting, here's an example:

docker images | grep -E '^golang.*latest' | awk -e '{print $3}' 

You'll need to tailor the regex in the grep to match your image name and tag.

yup.that way i did.but it is static.(every time i need to change the id,if content of image is modified).I need a dynamic id(some sort of variable) so that it will automatically fetch the updated image id from the repository. – Highclass

docker images --filter now supports searching by reference $ docker images --filter=reference='busy*:*libc' and also format to choose format of the output see the documentation – Dasya
