Build & Use Custom Docker images in your GitLab CI/CD pipeline

The public images from Dockerhub don't always contain all the dependencies you need. So instead of adding a lot of commands to your pipeline, I will show you how easy it is to build a custom Docker image with all the dependencies you need, push it to the GitLab Container Registry and use it in your pipeline.

Want to have ME be your GitLab & DevOps teacher? 🤔

[danielmuranyi]

Hey Valentin! I have only two subscriptions, one is for Dave2D and one for you. This is what I am looking for, I already bought one of you Udemy course to dig deeper in GitLab. Thanks for the great instructions and the very clarified description. I am trying to learn as much as I can beside my 5 days old second son :D

[raphaelpereira]

AMAZING CI/CD tutorial, but just to make it the best ever a link to the repo would be great.

[premierde]

Can you show how to use Kaniko, Buildah, Podman

[Invisileflyingdog]

I have build a docker image locally and push it to a registry that can be reached publicly (needed sign in ofc), but whenever I tried to use this image from gitlab runner after the before script to sign in it alwasys complianed the image pull failure..

[KVS]

I think this part should be in your CI/CD udemy course with deploying this image

[MilMike]

how can I use my custom image as a base image in my Dockerfile?
For example, my base image has all the dependencies and I want to use it to build my project. Is this possible? I tried to use it like so but it doesn't work:
FROM /myuser/myproject/base:v1.0.0
any ideas?

[EnderCrypt]

oh... your title is kinda easy to missunderstand, i was looking for a way to
"Build & Use Custom Docker images in your GitLab CI/CD pipeline"

specifically i want to BUILD images, from INSIDE the gitlab CI/CD pipeline

do you by any chance have any solution for this?

[hwynightkid]

I personally understand the thought that its bad practice to use latest.. but IMO.. it needs to be tested somewhere.. and for my personal proejcts I set latest.. so that at any time if something does break.. I find out about it right away.. otherwise things just run smoothly.. but I get in a job site that might not be tolerable to others

[wajidshaikh]

Good one, , can we see from scratch about git and there setup with Linux machine and how and where image and containers going to

[RuiDuartept]

Nice video, thanks for you work!
Would you be able to create a tutorial for building your own docker images locally?

[lorenzorava]

how did you handle the pull policy? if it is "if-not-present" the job never pull again your new image, but it will take always the previous...

[sebastiangehteuchnixan]

What if I have a docker-compose file ?
"docker-compose build -t $CI_REGISTRY_IMAGE ." does not work
How can I tag docker-compose ?

[omerguzel]

I adjust an image that have all dependencies inside of it. Is this the nearest or the exact process that I should do? I only need gitlab runner to fetch image from local not from docker hub but I couldn't find a way and this tutorial is similar to what I wanted. Am I wrong?

[erikwhitesides]

on my personal gitlab instance i had to register the gitlab runner with the shell executor,
then i had to use docker:20.10.10-dind for image

[teeesen]

Why build the Docker image on a schedule? Won’t it just build and push the same thing as it did the previous day if the Dockerfile hasn’t changed. And, if the Dockerfile has changed, wouldn’t you want to build a new image right away? Also, does it make sense to create and use a new tag each time the Dockerfile changes?

[hwynightkid]

I got your setup but.. when i go to apt install anything it says source not found? using ubuntu:20.04 it cannot find things as simple as apt install python3 .. I will go to the gitlab community next to see what I missed.. thanks for the great video tho to kick start my efforts

[TheMaurober]

Thanks for the video. I run this code to create a custom docker image but i get an error saying:
Cannot connect to the Docker daemon at tcp://docker:2375. Is the docker daemon running?
Any idea how can I solve this problem? I already set tls=false but still not working

[firo]

What is advantage of creating and using a yaml ci build file over a Dockerfile to create your image?

[ipcnmbe]

you did the build... but not the use...
