You can use GitLab CI/CD with Docker to create Docker images. Use the shell executor Recently I added pandas as a dependency and now it takes ages to run the pipelines. For my pipelines I am using docker-in-docker (dind). But, the documentation only refers to files that are stored on disk (node_modules, etc). Maybe its better, when you use kaniko.Its not good, when you build with dind. Docker layer cache. .. But we can try to go further. I am running a slef-hosted gitlab instance. This is my first day of using Gitlab, and so far, I'm very pleasantly surprised! Related posts. A Docker layer is the output of running a step defined in your Dockerfile. Cache in CI/CD is about saving directories or files across pipelines. Recent versions of Docker (Docker 1.13 and above) can use a pre-existing image as a cache during the docker build step, considerably speeding up the build process. This file defines the GitLab CI pipeline that will run when you push changes to your project. Use Docker to build Docker imagesall tiers. The Docker executor with the Docker image (Docker-in-Docker) Docker socket binding If you don't want to execute a runner in privileged mode, but want to use docker build, you can also use kaniko. Create a .gitlab-ci.yml file at the root of the repository. To run Docker commands in your CI/CD jobs, you must configure GitLab Runner to support docker commands. If you use any sane language package manager, somewhere on disk will be a global cache for your dependencies.. "/> Docker layer cache. For most of the projects, Docker layer caching is enough to optimize the build time. Building Docker images with GitLab CI/CD. GitLab CI/CD allows you to use Docker Engine to build and test docker-based projects. One of the new trends in Continuous Integration/Deployment is to: Create an application image. Run tests against the created image. Push image to a remote registry. Deploy to a server from the pushed image. A Docker layer is the output of running a step defined in your Dockerfile. A cache is one or more files a job downloads and saves. How cache is different from artifacts It is built off the previous layer before it (the parent) and contains the filesystem changes your step defined, files added, modified, or deleted. ENV PATH=/usr/local/bundle/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin. Head to the Git repository for the project you want to build images for. For most of the projects, Docker layer caching is enough to optimize the build time. But we can try to go further. Cache in CI/CD is about saving directories or files across pipelines.

Enable Docker layer caching for your production builds and save time and money. The following illustrates the use of Docker Layer Caching in Semaphore 2.0 projects: The .semaphore/semaphore.yml file has two blocks blocks. The Docker executor when used with GitLab CI, connects to Docker Engine and runs each build in a separate and isolated container using the predefined image that is set up in .gitlab-ci.yml and in accordance in config.toml. Subsequent jobs that use the same cache dont have to download the files again, so they execute more quickly. Then, to turn on the inline layer caching, use the BUILDKIT_INLINE_CACHE build argument. I build my container and run my tests on it.

I can see from the documentation, that its possible to cache dependencies between builds, and that the path is defined in the .gitlab-ci.yml. Finally, to use Docker in Docker, add a docker service: services: - name: docker:19.03.13-dind alias: docker # Using the same Docker image in a pipeline. Setting Up The Pull Through Cache The Docker page on Mirroring Docker Hub is very clear on how to set up a pull through cache. Possible fixes Adding the following line Instantly share code, notes, and snippets. If theres any file that changes in the layer, this will invalidate the cache, and its often something really silly. (danger note @ gitlab reference)kaniko offers the opportunity to use a cache-mechanism from the repository.kaniko@github. To enable BuildKit, set the DOCKER_BUILDKIT environment variable to 1. To learn how to define the cache in your .gitlab-ci.yml file, see the cache reference. Use the shell executor Shouldn't the Auto-DevOps.gitlab-ci.yml make a docker pull before making the docker build to leverage layer caching as the following page states : Keep in mind that any image that's used with the --cache-from argument must first be pulled (using docker pull) before it can be used as a cache source. Jobot is announcing a vacancy for the Permanent position of Software Engineer Angular, Node.js, SQL, Docker, Gitlab, Jira, REST APIs in Los In addition to speeding up job execution, a mirror can make your infrastructure more resilient to Docker Hub outages and Docker Hub rate limits. Our build time is now significantly reduced, thanks to docker layer caching. If you are using shared runners on GitLab.com, learn more about how these runners are configured. Here's the deployment spec for the Docker Dind pod which is going to provide docker services to Gitlab docker runner. Last active Oct 23, 2020 0 B Most of the time we set a name to the cache items to share them across jobs in multiple ways. GitLab Runner can use Docker to run jobs on user provided images. The fun of trying to munge together the: language dependency cache; language build cache; docker layer cache/reuse; ci system cache; dependencies. See full YAML example for a production build of a Rails application. Not sure if its your issue, but Ive found the that docker image layer cache on GitLab is very particular. Caching in GitLab CI/CD A cache is one or more files that a job downloads and saves. Subsequent jobs that use the same cache dont have to download the files again, so they execute more quickly. To learn how to define the cache in your.gitlab-ci.yml file, see the cache reference. # Caching in CI/CD. The only thing you need is a repository somewhere (I recommend Artifactory).With Artifactory you can also cache via the dind (see here). Once this is done, you can use the docker daemon in a Gitlab CI job spec file like this. docker buildx \ --tag your.registry/image:tag \ --push. This is possible with the use of Docker executor. How Docker caching works When running docker build, each command in Dockerfile results in a layer. If you are using shared runners on GitLab.com, learn more about how these runners are configured. Caching in GitLab CI/CD . To avoid building a Docker image at each job, it can be built in a first job, pushed to the image registry provided by GitLab, and pulled in the next jobs. The Docker executor with the Docker image (Docker-in-Docker) Docker socket binding If you don't want to execute a runner in privileged mode, but want to use docker build, you can also use kaniko. This results in the Registry as a pull through cache . We have our own runners. I would like to somehow cache my builds so I dont have to build the docker container everytime anew. The problem is that I am reading alot It is built off the previous layer before it (the parent) and contains the filesystem changes your step defined, files added, modified, or deleted. The first one creates a Docker image that is reused in the second blocks block using the --cache-from command line parameter. Now, expose the service, so Gitlab runners can connect with it. This requires special configuration of GitLab Runner to enable docker support during jobs. There are three methods to enable the use of docker build and docker run during jobs; each with their own tradeoffs. An alternative to using docker build is to use kaniko. This avoids having to execute Runner in privileged mode. I see youre using COPY .

Example: export DOCKER_BUILDKIT=1 # Build and cache image $ docker build --tag mjhea0/docker-ci-cache:latest --build-arg BUILDKIT_INLINE_CACHE=1 . In the previous article on how to use GitLab CI for CI/CD in a Kubernetes cluster, we basically used the Docker On Docker model for building images, because the Kubernetes cluster uses a container runtime like Docker, so we could mount the host docker.sock file from the host to the container to build the image, but recently we changed the container runtime to Containerd caching.
