To run it, we must create a container first.
#Docker mac os port software
To get a list of installed images: docker imagesĪn image is not a running process it is just the software needed to be launched.
#Docker mac os port download
For each layer, Docker will say if it is already present, or its download progress.
Versions 10.2, 10.3, 10.5 are also valid choices.
#Docker mac os port install
Note that, once a layer is downloaded for a certain image, Docker will not need to download it again for another image.įor example, if you want to install the default MariaDB image, you can type: docker pull mariadb:10.4 Some layers including necessary dependencies will be downloaded too. Once you have found an image that you want to use, you can download it via Docker. You can search Docker Hub (the official set of repositories) for an image with this command: docker search mariadb You can download a MariaDB image for Docker from the Offical Docker MariaDB, or choose another image that better suits your needs. The easiest way to use MariaDB on Docker is choosing a MariaDB image and creating a container. If you don't have dockerd running, you will get the following error for most docker commands:Ĭannot connect to the Docker daemon at unix: /var/run/docker.sock. On some systems you may have to start the dockerd daemon yourself: sudo systemctl start docker The script below will install the Docker repositories, required kernel modules and packages on the most common Linux distributions: curl -sSL | sh Installing Docker on Your System with the Universal Installation Script The Docker package could be called docker.io or docker-engine.įor information about installing Docker, see Get Docker in Docker documentation. Note that, while your package repositories could have a package called docker, it is probably not the Docker we are talking about. Docker is an open source project, released under the Apache License, version 2. It is used both in development and in production environments. Docker does not virtualize a whole system a container only includes the packages that are not included in the underlying system.ĭocker requires a very small amount of resources. A container is meant to run a specific daemon, and the software that is needed for that daemon to properly work. Docker is a framework that runs containers. In many cases, the best solution is using containers. However, this means installing a system on the top of another system. Or maybe, we simply want to isolate MariaDB from the rest of the system, to be sure that we won't cause any damage.Ī virtual machine would certainly serve the scope. Sometimes we want to install a specific version of MariaDB, MariaDB ColumnStore, or MaxScale on a certain system, but no packages are available.
