What to know before you install
README FIRST for Docker Toolbox and Docker Machine users
If you are already running Docker on your machine, first readDocker Desktop for Mac vs. Docker Toolbox to understand theimpact of this installation on your existing setup, how to set your environmentfor Docker Desktop on Mac, and how the two products can coexist.
Relationship to Docker Machine: Installing Docker Desktop on Mac does not affect machines you created with Docker Machine. You have the option to copy containers and images from your local
default
machine (if one exists) to the Docker Desktop HyperKit VM. Whenyou are running Docker Desktop, you do not need Docker Machine nodes running locally (or anywhere else). With Docker Desktop, you have a new, nativevirtualization system running (HyperKit) which takes the place of theVirtualBox system. To learn more, see Docker Desktop for Mac vs. Docker Toolbox.System requirements
Your Mac must meet the following requirements to successfully install Docker Desktop:
- Mac hardware must be a 2010 or a newer model, with Intel’s hardware support for memory management unit (MMU) virtualization, including Extended Page Tables (EPT) and Unrestricted Mode. You can check to see if your machine has this support by running the following command in a terminal:
sysctl kern.hv_support
If your Mac supports the Hypervisor framework, the command printskern.hv_support: 1
. - macOS must be version 10.14 or newer. That is, Mojave or Catalina. We recommend upgrading to the latest version of macOS.If you experience any issues after upgrading your macOS to version 10.15, you must install the latest version of Docker Desktop to be compatible with this version of macOS.Note: Docker supports Docker Desktop on the most recent versions of macOS. Docker Desktop currently supports macOS Mojave and macOS Catalina.As new major versions of macOS are made generally available, Docker stops supporting the oldest version and support the newest version of macOS.
- At least 4 GB of RAM.
- VirtualBox prior to version 4.3.30 must not be installed as it is not compatible with Docker Desktop.
What’s included in the installer
The Docker Desktop installation includes Docker Engine, Docker CLI client, Docker Compose, Notary, Kubernetes, and Credential Helper.
Install and run Docker Desktop on Mac
- Double-click
Docker.dmg
to open the installer, then drag the Docker icon to the Applications folder. - Double-click
Docker.app
in the Applications folder to start Docker. (In the example below, the Applications folder is in “grid” view mode.)The Docker menu in the top status bar indicates that Docker Desktop is running, and accessible from a terminal.If you’ve just installed the app, Docker Desktop launches the onboarding tutorial. The tutorial includes a simple exercise to build an example Docker image, run it as a container, push and save the image to Docker Hub. - Vlc mac 10.6.8 free download. Click the Docker menu () to seePreferences and other options.
- Select About Docker to verify that you have the latest version.
Congratulations! You are now successfully running Docker Desktop.
If you would like to rerun the tutorial, go to the Docker Desktop menu and select Learn.
Uninstall Docker Desktop
To unistall Docker Desktop from your Mac:
- From the Docker menu, select Troubleshoot and then select Uninstall.
- Click Uninstall to confirm your selection.
Note: Uninstalling Docker Desktop will destroy Docker containers and images local to the machine and remove the files generated by the application.
Switch between Stable and Edge versions
Docker Desktop allows you to switch between Stable and Edge releases. However, you can only have one version of Docker Desktop installed at a time. Switching between Stable and Edge versions can destabilize your development environment, particularly in cases where you switch from a newer (Edge) channel to an older (Stable) channel.
For example, containers created with a newer Edge version of Docker Desktop maynot work after you switch back to Stable because they may have been createdusing Edge features that aren’t in Stable yet. Keep this in mind asyou create and work with Edge containers, perhaps in the spirit of a playgroundspace where you are prepared to troubleshoot or start over.
Experimental features are turned on by default on Edge releases. However, when you switch from a Stable to an Edge release, you must turn on the experimental features flag to access experimental features. From the Docker Desktop menu, click Preferences > Command Line and then turn on the Enable experimental features toggle. Click Apply & Restart for the changes to take effect.
To safely switch between Edge and Stable versions, ensure you save images and export the containers you need, then uninstall the current version before installing another. For more information, see the section Save and Restore data below.
Save and restore data
You can use the following procedure to save and restore images and container data. For example, if you want to switch between Edge and Stable, or to reset your VM disk:
- Use
docker save -o images.tar image1 [image2 .]
to save any images you want to keep. See save in the Docker Engine command line reference. - Use
docker export -o myContainner1.tar container1
to export containers you want to keep. See export in the Docker Engine command line reference. - Uninstall the current version of Docker Desktop and install a different version (Stable or Edge), or reset your VM disk. Download crack photoshop cc mac.
- Use
docker load -i images.tar
to reload previously saved images. See load in the Docker Engine. - Use
docker import -i myContainer1.tar
to create a filesystem image corresponding to the previously exported containers. See import in the Docker Engine.

Sometimes we want to install a specific version of MariaDB, MariaDB Galera Cluster, or MaxScale on a certain system, but no packages are available. Or maybe, we simply want to isolate MariaDB from the rest of the system, to be sure that we won't cause any damage.
Mozilla 3.0 download mac. A virtual machine would certainly serve the scope. However, this means installing a system on the top of another system. It requires a lot of resources.
In many cases, the best solution is Docker. Docker is a framework that runs containers. A container is meant to run a specific daemon, and the software that is needed for that daemon to properly work. Docker does not virtualize a whole system; a container only includes the packages that are not included in the underlying system.
Docker requires a very small amount of resources. It can run on a virtualized system. It is used both in development and in production environments.
Docker is an open source project, released under the Apache License, version 2.
Note that, while your package repositories could have a package called
docker
, it is probably not the Docker we are talking about. The Docker package could be called docker.io
or docker-engine
.Installing Docker on Your System with the Universal Installation Script
The script below will install the Docker repositories, required kernel modules and packages on the most common Linux distributions:
Starting dockerd
On some systems you may have to start the
dockerd daemon
yourself:If you don't have
dockerd
running, you will get the following error for most docker
commands:Using MariaDB Images
The easiest way to use MariaDB on Docker is choosing a MariaDB image and creating a container.
Downloading an Image
You can download a MariaDB image for Docker from the Offical MariaDB Repository, or choose another image that better suits your needs. You can search Docker Hub (the official set of repositories) for an image with this command:
Once you have found an image that you want to use, you can download it via Docker. Some layers including necessary dependencies will be downloaded too. Note that, once a layer is downloaded for a certain image, Docker will not need to download it again for another image.
For example, if you want to install the default MariaDB image, you can type:
This will install the 10.4 version. Versions 10.1, 10.2 and 10.3 are also valid choices.
You will see a list of necessary layers. For each layer, Dockers will say if it is already present, or its download progress.
To get a list of installed images:
Creating a Container
An image is not a running process; it is just the software needed to be launched. To run it, we must create a container first. The command needed to create a container can usually be found in the image documentation. For example, to create a container for the official MariaDB image:
mariadbtest
Free antivirus download for windows 8 phone. is the name we want to assign the container. If we don't specify a name, an id will be automatically generated.10.1 and 10.2 are also valid target versions:
Optionally, after the image name, we can specify some options for mysqld. https://dysupernal273.weebly.com/download-free-bible-app-for-java-phone.html. For example:
Docker will respond with the container's id. Oovoo download for mac desktop. But, just to be sure that the container has been created and is running, we can get a list of running containers in this way:
We should get an output similar to this one:
Running and Stopping the Container
Docker allows us to restart a container with a single command:
The container can also be stopped like this:
The container will not be destroyed by this command. The data will still live inside the container, even if MariaDB is not running. To restart the container and see our data, we can issue:
With
docker stop
, the container will be gracefully terminated: a SIGTERM
signal will be sent to the mysqld
process, and Docker will wait for the process to shutdown before returning the control to the shell. However, it is also possible to set a timeout, after which the process will be immediately killed with a SIGKILL
. Or it is possible to immediately kill the process, with no timeout.In case we want to destroy a container, perhaps because the image does not suit our needs, we can stop it and then run:
Note that the command above does not destroy the data volume that Docker has created for /var/lib/mysql. If you want to destroy the volume as well, use:
Pausing Containers
A container can also be frozen with the
pause
command. Docker will freeze the process using croups. MariaDB will not know that it is being frozen and, when we unpause
it, MariaDB will resume its work as expected.Both
pause
and unpause
accept one or more container names. So, if we are running a cluster, we can freeze and resume all nodes simultaneously:Pausing a container is very useful when we need to temporarily free our system's resources. If the container is not crucial at this moment (for example, it is performing some batch work), we can free it to allow other programs to run faster.
Troubleshooting a Container
If the container doesn't start, or is not working properly, we can investigate with the following command:
This command shows what the daemon sent to the stdout since the last attempt of starting - the text that we typically see when we invoke
mysqld
from the command line.On some systems, including recent Ubuntu releases, commands such as
docker stop mariadbtest
and docker restart mariadbtest
may fail with a permissions error. This can be caused by the AppArmor package, and even sudo
won't allow you to execute the command. You can totally remove AppArmor using the following commands:Restarting the system will then allow Docker to operate normally. More information is available in the Docker forums: https://forums.docker.com/t/can-not-stop-docker-container-permission-denied-error/41142/3
Accessing the Container
To access the container via Bash, we can run this command:
Now we can use normal Linux commands like cd, ls, etc. We will have root privileges. We can even install our favorite file editor, for example:
In some images, no repository is configured by default, so we may need to add them.
Mario kart games free download. Note that if we run mysqladmin shutdown or the SHUTDOWN command to stop the container, the container will be deactivated, and we will automatically exit to our system.
Connecting to MariaDB from Outside the Container
If we try to connect to the MariaDB server on
localhost
, the client will bypass networking and attempt to connect to the server using a socket file in the local filesystem. However, this doesn't work when MariaDB is running inside a container because the server's filesystem is isolated from the host. The client can't access the socket file which is inside the container, so it fails to connect.Therefore connections to the MariaDB server must be made using TCP, even when the client is running on the same machine as the server container.
Most MariaDB images, including the official one, have external TCP connections disabled using the
bind-address
option in their #my.cnf# file. The docker image used in this guide is based on Ubuntu, so the file is located at /etc/mysql/my.cnf
.To use MariaDB we will need to edit the configuration file to change the appropriate option, and then restart the container.
Inside the container, edit the file
my.cnf
and check for the line that begins bind-address
. Put a hash at the start of the line to comment it out:Save the file.
While still inside the container, send the shutdown command to MariaDB. This will shut down the server and also exit back out to the host:
Start the container again. This time the MariaDB server will have networking enabled:
Find the IP address that has been assigned to the container:
You can now connect to the MariaDB server using a TCP connection to that IP address.
Forcing a TCP Connection
After enabling network connections in MariaDB as described above, we will be able to connect to the server from outside the container.
On the host, run the client and set the server address ('-h') to the container's IP address that you found in the previous step:
This simple form of the connection should work in most situations. Depending on your configuration, it may also be necessary to specify the port for the server or to force TCP mode:
Port Configuration for Clustered Containers and Replication
Multiple MariaDB servers running in separate Docker containers can connect to each other using TCP. This is useful for forming a Galera cluster or for replication.
When running a cluster or a replication setup via Docker, we will want the containers to use different ports. The fastest way to achieve this is mapping the containers ports to different port on our system. We can do this when creating the containers (
docker run
command), by using the -p
option, several times if necessary. For example, for Galera nodes we will use a mapping similar to this one:Installing MariaDB on Another Image
It is possible to download a Linux distribution image, and to install MariaDB on it. This is not much harder than installing MariaDB on a regular operating system (which is easy), but it is still the hardest option. Normally we will try existing images first. However, it is possible that no image is available for the exact version we want, or we want a custom installation, or perhaps we want to use a distribution for which no images are available. In these cases, we will install MariaDB in an operating system image.
Daemonizing the Operating System
First, we need the system image to run as a daemon. If we skip this step, MariaDB and all databases will be lost when the container stops.
To demonize an image, we need to give it a command that never ends. In the following example, we will create a Debian Jessie daemon that constantly pings the 8.8.8.8 special address:
Installing MariaDB
At this point, we can enter the shell and issue commands. First we will need to update the repositories, or no packages will be available. We can also update the packages, in case some of them are newer than the image. Then, we will need to install a text editor; we will need it to edit configuration files. For example:
Now we are ready to install MariaDB in the way we prefer.
