Docker Alpine Install

Ruby is a dynamic, reflective, object-oriented, general-purpose, open-source programming language. In this lab we will learn how to install certbot using the official nginx:alpine docker image and use it to create a SSL certificate for our domain. Note that in order to make it work you must own the domain for which you'll be fetching a certificate and it must resolve to the public IP address where the docker container is exposed. Install Compose on Linux systems. On Linux, you can download the Docker Compose binary from the Compose repository release page on GitHub.Follow the instructions from the link, which involve running the curl command in your terminal to download the binaries. The following multi-platform Docker images are available: gitlab/gitlab-runner:latest based on Ubuntu. Gitlab/gitlab-runner:alpine based on Alpine with much a smaller footprint (160/350 MB Ubuntu vs 45/130 MB Alpine compressed/decompressed). See GitLab Runner source for possible build instructions for both Ubuntu and Alpine images.

Install the Docker image and start the container
This is how you can run GitLab Runner inside a Docker container.

General GitLab Runner Docker image usageGitLab Runner Docker images (based on Ubuntu or Alpine Linux)are designed as wrappers around the standard gitlab-runner command, like ifGitLab Runner was installed directly on the host.
The general rule is that every GitLab Runner command that normally would be executedas:
can be executed with:
For example, getting the top-level help information for GitLab Runner command could beexecuted as:
In short, the gitlab-runner part of the command is replaced withdocker run [docker options] gitlab/gitlab-runner, while the rest of thecommand stays as it is described in the register documentation.The only difference is that the gitlab-runner command is executed inside of aDocker container.
Install the Docker image and start the containerBefore you begin, ensure Docker is installed.
To run gitlab-runner inside a Docker container, you need to make sure that the configuration is not lost when the container is restarted. To do this, there are two options, which are described below.
Make sure that you read the FAQ section which describes some of the most common problems with GitLab Runner.
If you are using a session_server, you will also need to expose port 8093 by adding -p 8093:8093 to your docker run command.
Option 1: Use local system volume mounts to start the Runner container

Option 1: Use local system volume mounts to start the Runner containerThis example uses the local system for the configuration volume that is mounted into the gitlab-runner container. This volume is used for configs and other resources.
Option 2: Use Docker volumes to start the Runner containerDownload catalina app store. In this example, you can use a configuration container to mount your custom data volume.
Create the Docker volume:
Start the GitLab Runner container using the volume we just created:
To set the container's timezone, in the docker run command, use the flag --env TZ=. View a list of available time zones.
Register the runnerThe final step is to register a new runner. The GitLab Runner Container won't pick up any jobs until it's registered.
Update configurationDocker Alpine Install GitAdobe photoshop 2020 for mac download. If you change the configuration in config.toml, you might need to restart the runner to apply the change.Make sure to restart the whole container instead of using gitlab-runner restart:
Upgrade versionPull the latest version (or a specific tag):
Stop and remove the existing container:
Start the container as you did originally: Macbook allow downloads from anywhere.
You need to use the same method for mounting you data volume as youdid originally (-v /srv/gitlab-runner/config:/etc/gitlab-runner or--volumes-from gitlab-runner-config).
Docker Alpine InstallationReading GitLab Runner logsWhen GitLab Runner is started as a foreground task (whether it's a locally installed binary orinside of a Docker Container), the logs are printed to the standard output. WhenGitLab Runner is started as a system service (e.g. with Systemd), the logs are in mostcases logged through Syslog or other system logging mechanism.
With GitLab Runner started as a Docker based service, since the gitlab-runner .. command isthe main process of the container, the logs can be read using the docker logs command.
For example, if GitLab Runner was started with the following command:
you may get the logs with:
Docker Alpine Install Curlwhere gitlab-runner is the name of the container, set with --name gitlab-runner bythe first command.
You may find more information about handling container logs at the Docker documentationpage.
Installing trusted SSL server certificatesIf your GitLab CI server is using self-signed SSL certificates then you shouldmake sure the GitLab CI server certificate is trusted by the GitLab Runnercontainer for them to be able to talk to each other.
The gitlab/gitlab-runner image is configured to look for the trusted SSLcertificates at /etc/gitlab-runner/certs/ca.crt, this can however be changed using the-e 'CA_CERTIFICATES_PATH=/DIR/CERT' configuration option.
Copy the ca.crt file into the certs directory on the data volume (or container).The ca.crt file should contain the root certificates of all the servers youwant GitLab Runner to trust. The GitLab Runner container willimport the ca.crt file on startup so if your container is already running youmay need to restart it for the changes to take effect.
Docker imagesThe following multi-platform Docker images are available:
gitlab/gitlab-runner:latest based on Ubuntu.
gitlab/gitlab-runner:alpine based on Alpine with much a smaller footprint(~160/350 MB Ubuntu vs ~45/130 MB Alpine compressed/decompressed).
See GitLab Runnersource for possible build instructions for both Ubuntu and Alpine images.
The IBM Z image does not contain the docker-machine dependency, as it is not yet maintained for the Linux s390xplatform. See issue for current status.
SELinuxSome distributions (CentOS, RedHat, Fedora) use SELinux by default to enhance the security of the underlying system.
Special care must be taken when dealing with such a configuration.
If you want to use the Docker executor to run builds in containers, you'll need access to /var/run/docker.sock.However, if SELinux is in enforcing mode, you will see a Permission denied error when you're accessing /var/run/docker.sock.Install selinux-dockersock to resolve this issue.
Make sure that a persistent directory is created on host: mkdir -p /srv/gitlab-runner/config.
Run Docker with :Z on volumes:
