(Be sure to checkout the FREE - you get a weekly email packed with all the essential knowledge you need to know about performance tuning on SQL Server.) Years ago when I switched from Windows to Mac, people have told me regularily that I’m crazy. How can I be that stupid to work on MacOS when I’m dependent on SQL Server? In my case it wasn’t that terrible, because my main work is about content creation (writing blog postings, articles, presentations, training videos) and very often I was only connecting through a RDP connection to a remote SQL Server. Therefore running natively on MacOS was not a big deal for me, and for the last resort I always have a Windows VM which runs in VMware Fusion on my Mac.

But since the introduction of the Container concept through Docker and the possibility to run SQL Server directly in a Container, my life was changing even better. Because now I can run SQL Server 2017+ directly on my Mac and I even don’t really need a Windows VM anymore. In this blog posting I want to show you how you can do the same and run SQL Server directly on your Mac in a Docker container. Installing SQL Server in a Docker Container Before you can install SQL Server in a Docker Container on the Mac, you have to install and configure of course Docker itself.

I don’t want to go into the details how to install Docker itself, because the necessary steps are. Before you can create a Docker Container for SQL Server, you have to pull the correct Docker Image from the Docker Registry. In my case I have decided to try out the latest CTP version of SQL Server 2019: docker pull mcr.microsoft.com/mssql/server:2019-CTP2.1-ubuntu When you have pulled the image, you can see it with the docker images command in your Terminal: You can think about a Docker Image like an ISO file: it’s just an image, and you can’t run it directly, because you have to install it.

Therefore we also have to “install” the pulled Docker Image. In Docker you can “install” an image by running it. And that creates the actual Docker Container, which is finally the exectuable that you are executing. Let’s run our Docker Image with the docker run command: docker run -e ‘ACCEPTEULA=Y’ -e ‘SAPASSWORD=passw0rd1!’ -p 1433:1433 –name sql2019ctp2 -d mcr.microsoft.com/mssql/server:vNext-CTP2.0-ubuntu As you can see from the command line, you have to pass in a lot of different parameters. Let’s have a more detailed look on them:.e ‘ACCEPTEULA=Y’. With the -e option you set an environment variable, on which SQL Server is dependent on.

In our case we have to accept the EULA to be able to use SQL Server.e ‘SAPASSWORD=passw0rd1!‘. With the SAPASSWORD environment variable we set the password for the SA login.p 1433:1433. With the -p option we bind a port on our host machine (in my case on the Mac) to a port in the Container. The port on the left side of the colon is the port on the host machine, and the port on the right side of the colon is the port in the Container. In my case I bind the default SQL Server port of 1433 within the Container to the port 1433 on my Mac.

Therefore I can directly access the exposed SQL Server Container through the IP address of my Mac on the network. If you have multiple SQL Server Containers, you can also bind them to different ports on your host machine to access them independently from each other. –name. With the –name option we assign a custom name to our Docker Container.d.

And with the -d option we specify the Docker Image that we have pulled previously, and that you want to run the Docker Container detached from the Terminal. This just means that you can close your Terminal, and your Docker Container is still running in the background. After you have executed that Docker command, your Docker Container is up and running. Accessing SQL Server on a Mac We have now 2019 up and running in a Docker Container.

But how do we access SQL Server? Of course, I can start up a Windows VM, and use SQL Server Management Studio to access SQL Server. But then I’m again dependent on a Windows VM, which also needs periodically updates, and it would be also a huge overhead to deploy a whole Windows VM just for SQL Server Management Studio Therefore let’s introduce! Azure Data Studio was formerly known as SQL Operations Studio and it is a client application with which you can manage SQL Server – natively on!!! As you can see from the previous picture, I have connected here directly to localhost, because in the last step we have exposed the port 1433 of the Docker Container to our host machine.

Don’t get me wrong: compared to SQL Server Management Studio, Azure Data Studio is “nice” but 😉 But hey, I can run it directly on my Mac (without the need of a Windows VM), I can run SQL statements, I have access to Estimated and Actual Execution Plans, and very importantly – it’s extensible. What do I need more? For the kind of work that I’m doing, it’s enough. Restoring your first Database When you look back to the previous picture, you can see that you got a vanilla installation of SQL Server 2019. There are our system databases, the crazy default settings, and that’s it. There are of course currently no other database.

So you have to create your own databases, or you take an existing database (maybe from a Windows-based SQL Server installation) and you restore it in your Docker Container. Let’s do that now. In my case I want to show you now the necessary steps how to restore AdventureWorks in the Docker Container.

First of all you have to copy your backup file into the Docker Container. But you can’t do a regular cp command from the Terminal, because that command has no idea about your Docker Container. Makes somehow sense Therefore your Docker installation offers you the command cp with which you can copy a local file into a Docker Container and vice versa. Let’s take now our backup of AdventureWorks and copy it into the folder /var/backups of our Docker Container: docker cp AdventureWorks2014.bak sql2019ctp2:/var/backups/AdventureWorks2014.bak After you have copied the backup file, we can now restore the database. But the destination folders are different as on a Windows-based SQL Server installation, therefore we also have to move our data and log files. Therefore I have executed in the first step the following command to get the logical file names of our database backup.

RESTORE FILELISTONLY FROM DISK = ‘/var/backups/AdventureWorks2014.bak’ And based on that information, let’s perform now the restore of our database. RESTORE DATABASE AdventureWorks2014 FROM DISK = ‘/var/backups/AdventureWorks2014.bak’ WITH MOVE ‘AdventureWorks2014Data’ TO ‘/var/opt/mssql/data/Adventureworks2014.mdf’, MOVE ‘AdventureWorks2014Log’ TO ‘/var/opt/mssql/data/Adventureworks2014.ldf’ As you can see I’m moving the data and log files into the folder /var/opt/mssql/data. And now we have our AdventureWorks database restored in our Docker Container.

When you are finished with your work in your Docker Container, you can stop the Container with the following command: docker stop sql2019ctp2 And with a docker start command, you can restart your Container again: docker start sql2019ctp2 In that case, all the changes that you have done in your Docker Container (like restoring the AdventureWorks database), are persisted across restarts. Summary Running SQL Server natively on a Mac or on Linux was always a huge April fool. But with the introduction of Docker, and the SQL Server support for it, it’s now real. You can now run natively SQL Server on the Mac, and with the help of Azure Data Studio you can even access SQL Server with a native MacOS application.

We have really exiting times ahead of us! Thanks for your time, -Klaus. 'This training on SQL Server performance tuning was extremely interesting.

Klaus taught me lot of things I was not aware of. I especially loved the tips he gave on common mistakes and wrong concepts about SQL Server.

Such information, coming from an independent expert (“expert” is still very understimated when talking about Klaus’ knowledge), is a lot more valuable than spending hours reading and googling. This training has a high return on investment and anyone who is seriously working with SQL Server should attend this workshop.'

$ docker run hello-world Unable to find image 'hello-world:latest' locally latest: Pulling from library/hello-world ca4f61b1923c: Pull complete Digest: sha256:ca0eeb6fb05351dfc8759c20733c91def84cb8007aa89a5bf606bc8b315b9fc7 Status: Downloaded newer image for hello-world:latest Hello from Docker! This message shows that your installation appears to be working correctly. Start a Dockerized web server.

Like the hello-world image above, if the image is not found locally, Docker pulls it from Docker Hub. $ docker run -d -p 80:80 -name webserver nginx. In a web browser, go to to view the nginx homepage. Because we specified the default HTTP port, it isn’t necessary to append:80 at the end of the URL.

Early beta releases used docker as the hostname to build the URL. Now, ports are exposed on the private IP addresses of the VM and forwarded to localhost with no other host name set.

View the details on the container while your web server is running (with docker container ls or docker ps): $ docker container ls CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 90 nginx 'nginx -g 'daemon off' About a minute ago Up About a minute 0.0.0.0:80-80/tcp, 443/tcp webserver. Stop and remove containers and images with the following commands. Use the “all” flag ( -all or -a) to view stopped containers. $ docker container ls $ docker container stop webserver $ docker container ls -a $ docker container rm webserver $ docker image ls $ docker image rm nginx Preferences menu Choose → Preferences from the menu bar and configure the runtime options described below. General General settings are:. Start Docker when you log in: Uncheck this option if you don’t want Docker to start when you open your session. Automatically check for updates notifies you when an update is available.

Click OK to accept and install updates (or cancel to keep the current version). If you disable this option, you can still find out about updates manually by choosing → Check for Updates. Include VM in Time Machine backups backs up the Docker for Mac virtual machine.

(Disabled by default.). Securely store Docker logins in MacOS keychain stores your Docker login credentials. (Enabled by default.).

Send usage statistics — Send diagnostics, crash reports, and usage data to Docker. This information helps Docker improve the application and get more context for troubleshooting problems. (Enabled by default.) File sharing Choose which local directories to share with your containers.

File sharing is required for volume mounting if the project lives outside of the /Users directory. In that case, share the drive where the Dockerfile and volume are located. Otherwise, you get file not found or cannot start service errors at runtime. File share settings are:. Add a Directory: Click + and navigate to the directory you want to add. Apply & Restart makes the directory available to containers using Docker’s bind mount ( -v) feature. There are some limitations on the directories that can be shared:.

They cannot be a subdirectory of an already shared directory. They cannot already exist inside of Docker. For more information, see:. in the topic on.) Advanced On the Advanced tab, you can limit resources available to Docker.

Advanced settings are: CPUs: By default, Docker for Mac is set to use half the number of processors available on the host machine. To increase processing power, set this to a higher number; to decrease, lower the number. Memory: By default, Docker for Mac is set to use 2 GB runtime memory, allocated from the total available memory on your Mac.

To increase RAM, set this to a higher number; to decrease it, lower the number. Swap: Configure swap file size as needed. The default is 1 GB. Disk Specify the Disk image location of the Linux volume, where containers and images are stored. You can also move the disk image location. If you attempt to move the disk image to a location that already has one, you get a prompt asking if you want to use the existing image or replace it. Proxies Docker for Mac detects HTTP/HTTPS Proxy Settings from macOS and automatically propagates these to Docker and to your containers.

For example, if you set your proxy settings to Docker uses this proxy when pulling containers. When you start a container, your proxy settings propagate into the containers. $ docker run -it alpine env PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin HOSTNAME=b7edf988b2b5 TERM=xterm HOME=/root HTTPPROXY=httpproxy=noproxy=.local, 169.254/16 You can see from the above output that the HTTPPROXY, httpproxy, and noproxy environment variables are set. When your proxy configuration changes, Docker restarts automatically to pick up the new settings.

If you have containers that you wish to keep running across restarts, you should consider using. Daemon You can configure options on the Docker daemon that determine how your containers run. Select Basic to configure the daemon with interactive settings, or select Advanced to edit the JSON directly. Experimental features Both Docker for Mac Stable and Edge releases have experimental features enabled on Docker Engine, as described. If you uncheck experimental mode, Docker for Mac uses the current generally available release of Docker Engine. Don’t enable experimental features in production Experimental features are not appropriate for production environments or workloads.

They are meant to be sandbox experiments for new ideas. Some experimental features may become incorporated into upcoming stable releases, but others may be modified or pulled from subsequent Edge releases, and never released on Stable. You can see whether you are running experimental mode at the command line. If Experimental is true, then Docker is running in experimental mode, as shown here. (If false, Experimental mode is off.).

$ kubectl config get-contexts $ kubectl config use-context docker-for-desktop If you installed kubectl with Homebrew, or by some other method, and experience conflicts, remove /usr/local/bin/kubectl. To enable Kubernetes support and install a standalone instance of Kubernetes running as a Docker container, select Enable Kubernetes, choose the and click the Apply button. An Internet connection is required. Images required to run the Kubernetes server are downloaded and instantiated as containers, and the /usr/local/bin/kubectl command is installed on your Mac. When Kubernetes is enabled and running, an additional status bar item displays at the bottom right of the Docker for Mac Preferences dialog.

The status of Kubernetes shows in the Docker menu and the context points to docker-for-desktop. By default, Kubernetes containers are hidden from commands like docker service ls, because managing them manually is not supported.

To make them visible, select Show system containers (advanced) and click Apply and restart. Most users do not need this option. To disable Kubernetes support at any time, deselect Enable Kubernetes. The Kubernetes containers are stopped and removed, and the /usr/local/bin/kubectl command is removed. For more about using the Kubernetes integration with Docker for Mac, see. Reset Select - Preferences from the menu bar, then click Reset to reset factory defaults, restart the Docker daemon, or uninstall. Reset settings are:.

Restart - Select to restart the Docker daemon. Remove all data - This option removes/resets all Docker data without a reset to factory defaults (which would cause you to lose settings). Reset to factory defaults - Choose this option to reset all options on Docker for Mac to its initial state, the same as when it was first installed. Uninstall - Choose this option to remove Docker for Mac from your system.

Uninstall Docker for Mac from the commandline To uninstall Docker from Mac from a terminal, run: -uninstall. If your instance is installed in the default location, this command provides a clean uninstall. $ /Applications/Docker.app/Contents/MacOS/Docker -uninstall Docker is running, exiting.

Docker uninstalled successfully. You can move the Docker application to the trash. You might want to use the command-line uninstall if, for example, you find that the app is non-functional, and you cannot uninstall it from the menu. Add TLS certificates You can add trusted Certificate Authorities (CAs) (used to verify registry server certificates) and client certificates (used to authenticate to registries) to your Docker daemon. Add custom CA certificates (server side) All trusted CAs (root or intermediate) are supported. Docker for Mac creates a certificate bundle of all user-trusted CAs based on the Mac Keychain, and appends it to Moby trusted certificates. So if an enterprise SSL certificate is trusted by the user on the host, it is trusted by Docker for Mac.

To manually add a custom, self-signed certificate, start by adding the certificate to the macOS keychain, which is picked up by Docker for Mac. Here is an example. $ security add-trusted-cert -d -r trustRoot -k /Library/Keychains/login.keychain ca.crt See also,. Note: You need to restart Docker for Mac after making any changes to the keychain or to the /.docker/certs.d directory in order for the changes to take effect. For a complete explanation of how to do this, see the blog post.

Add client certificates You can put your client certificates in /.docker/certs.d/:/client.cert and /.docker/certs.d/:/client.key. When the Docker for Mac application starts up, it copies the /.docker/certs.d folder on your Mac to the /etc/docker/certs.d directory on Moby (the Docker for Mac xhyve virtual machine).

You need to restart Docker for Mac after making any changes to the keychain or to the /.docker/certs.d directory in order for the changes to take effect. The registry cannot be listed as an insecure registry (see ). Docker for Mac ignores certificates listed under insecure registries, and does not send client certificates. Commands like docker run that attempt to pull from the registry produce error messages on the command line, as well as on the registry. Directory structures for certificates If you have this directory structure, you do not need to manually add the CA certificate to your Mac OS system login.

/Users//.docker/certs.d/ └──: ├── client.cert └── client.key To learn more about how to install a CA root certificate for the registry and how to set the client TLS certificate for verification, see in the Docker Engine topics. Install shell completion Docker for Mac comes with scripts to enable completion for the docker, docker-machine, and docker-compose commands. The completion scripts may be found inside Docker.app, in the Contents/Resources/etc/ directory and can be installed both in Bash and Zsh. Bash Bash has To activate completion for Docker commands, these files need to be copied or symlinked to your bashcompletion.d/ directory. For example, if you installed bash via. Etc =/Applications/Docker.app/Contents/Resources/etc ln -s $etc/docker.bash-completion $(brew -prefix )/etc/bashcompletion.d/docker ln -s $etc/docker-machine.bash-completion $(brew -prefix )/etc/bashcompletion.d/docker-machine ln -s $etc/docker-compose.bash-completion $(brew -prefix )/etc/bashcompletion.d/docker-compose Zsh In Zsh, the takes care of things. To activate completion for Docker commands, these files need to be copied or symlinked to your Zsh site-functions/ directory.

For example, if you installed Zsh via. Etc =/Applications/Docker.app/Contents/Resources/etc ln -s $etc/docker.zsh-completion /usr/local/share/zsh/site-functions/docker ln -s $etc/docker-machine.zsh-completion /usr/local/share/zsh/site-functions/docker-machine ln -s $etc/docker-compose.zsh-completion /usr/local/share/zsh/site-functions/docker-compose Give feedback and get help To get help from the community, review current user topics, join or start a discussion, log on to our.
