Docker registries also allow the creation of notifications based on events. Docker Hub is the default registry where Docker looks for images. Two main public registries are Docker Hub and Docker Cloud.

Docker clients connect to registries to download ("pull") images for use or upload ("push") images that they have built.

  • Registries: A Docker registry is a repository for Docker images.
  • The result is known as a swarm, a set of cooperating daemons that communicate through the Docker API.
  • A Docker service allows containers to be scaled across multiple Docker daemons.
  • Images are used to store and ship applications.
  • A Docker image is a read-only template used to build containers.
  • A container is managed using the Docker API or CLI.
  • A Docker container is a standardized, encapsulated environment that runs applications.
  • The main classes of Docker objects are images, containers, and services.
  • Objects: Docker objects are various entities used to assemble an application in Docker.
  • The Docker client program, called docker, provides a command-line interface, CLI, that allows users to interact with Docker daemons. The daemon listens for requests sent via the Docker Engine API.

    Software: The Docker daemon, called dockerd, is a persistent process that manages Docker containers and handles container objects.

    The Docker software as a service offering consists of three components: Docker containers are standard processes, so it is possible to use kernel features to monitor their execution - including for example the use of tools like strace to observe and intercede with system calls. ĭocker implements a high-level API to provide lightweight containers that run processes in isolation. Since version 0.9, Docker includes its own component (called " libcontainer") to use virtualization facilities provided directly by the Linux kernel, in addition to using abstracted virtualization interfaces via libvirt, LXC and systemd-nspawn. The Linux kernel's support for namespaces mostly isolates an application's view of the operating environment, including process trees, network, user IDs and mounted file systems, while the kernel's cgroups provide resource limiting for memory and CPU. A 2018 analysis found that a typical Docker use case involves running eight containers per host, and that a quarter of analyzed organizations run 18 or more per host. īecause Docker containers are lightweight, a single server or virtual machine can run several containers simultaneously. Docker on macOS uses a Linux virtual machine to run the containers. When running on Linux, Docker uses the resource isolation features of the Linux kernel (such as cgroups and kernel namespaces) and a union-capable file system (such as OverlayFS) to allow containers to run within a single Linux instance, avoiding the overhead of starting and maintaining virtual machines. This enables the application to run in a variety of locations, such as on-premises, in a public cloud, and/or in a private cloud. ĭocker can package an application and its dependencies in a virtual container that can run on any Linux, Windows, or macOS computer.

    However, you can upgrade the image’s OS before it is available in the GitLab repositories.Docker can use different interfaces to access virtualization features of the Linux kernel. Source for possible build instructions for both Ubuntu and Alpine images.Īs of, the GitLab Runner Docker image based on Alpine uses Alpine 3.12.0. (~160/350 MB Ubuntu vs ~45/130 MB Alpine compressed/decompressed).

  • gitlab/gitlab-runner:alpine based on Alpine with much a smaller footprint.
  • gitlab/gitlab-runner:latest based on Ubuntu.
  • The following multi-platform Docker images are available: Your container is already running you may need to restart it for the changes to take effect. The GitLab Runner container imports the ca.crt file on startup so if The ca.crt file should contain the root certificates of all the servers you e "CA_CERTIFICATES_PATH=/DIR/CERT" configuration option.Ĭopy the ca.crt file into the certs directory on the data volume (or container). The gitlab/gitlab-runner image is configured to look for the trusted SSLĬertificates at /etc/gitlab-runner/certs/ca.crt, this can however be changed using the

    Make sure the GitLab CI server certificate is trusted by the GitLab RunnerĬontainer for them to be able to talk to each other. If your GitLab CI server is using self-signed SSL certificates then you should Installing trusted SSL server certificates You may find more information about handling container logs at the Docker documentation Where gitlab-runner is the name of the container, set with -name gitlab-runner by
