Data Cargo In The Clouds – Running SQL Server 2017 in Docker

sqlserver_and_docker

In my previous post I attempted to explain my new interest in Docker and running data-centric applications in container. Starting here I will show how to install SQL Server for Linux on Azure IaaS in container.

Lets start by creating Linux VM in Azure that will run Docker for us.  I dont want to spend all of the time and space going through steps in portal or PowerShell since I already went through these in this post, Good video titorial  can also be found here .

Assuming you successfully created Linux VM and can login like this:

azlinux1

Next thing we will install Docker on that VM.  We will get latest and greatest version of Docker from Docker repository.

  • First, add the GPG key for the official Docker repository to the system:

    $ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
    
  • Add the Docker repository to APT sources:

    $ sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
  • Next, update the package database with the Docker packages from the newly added repo:

    $ sudo apt-get update
  • Make sure you are about to install from the Docker repo instead of the default Ubuntu 16.04 repo:
    apt-cache policy docker-ce

    You should see following output:

    docker-ce:
      Installed: (none)
      Candidate: 17.03.1~ce-0~ubuntu-xenial
      Version table:
         17.03.1~ce-0~ubuntu-xenial 500
            500 https://download.docker.com/linux/ubuntu xenial/stable amd64 Packages
         17.03.0~ce-0~ubuntu-xenial 500
            500 https://download.docker.com/linux/ubuntu xenial/stable amd64 Packages
    
    

    Notice that docker-ce is not installed, but the candidate for installation is from the Docker repository for Ubuntu 16.04. The docker-ce version number might be different.

  • Finally install Docker
    $ sudo apt-get install -y docker-ce
  • Make sure its installed and running
    $ sudo systemctl status docker

    Output should be similar to below showing that daemon is started and running

    linuxdoc

Next we need to pull latest SQL Server Docker image:

$ sudo docker pull microsoft/mssql-server-linux

Once the image is pulled and extracted you should see similar output

linuxdoc2

Now lets run container image with Docker:

$ sudo docker run -e 'ACCEPT_EULA=Y' -e 'MSSQL_SA_PASSWORD=<YourStrong!Passw0rd>' -e 'MSSQL_PID=Developer' --cap-add SYS_PTRACE -p 1401:1433 -d microsoft/mssql-server-linux

Now we are running Docker container with SQL Server 2017 in Azure. We should be able to list our containers like:

 $ sudo docker ps -a

And see output like:

linuxdoc3

Connect to SQL Server in the container.

The following steps use the SQL Server command-line tool, sqlcmd, inside the container to connect to SQL Server. First lets connect to bash inside the container using docker exec command. Note I am providing container id here as parameter fetched from previous output of ps command

$ sudo docker exec -it d95734b7f9ba  "bash"

Now lets connect via sqlcmd here

/opt/mssql-tools/bin/sqlcmd -S localhost -U SA -P '<YourStrong!Passw0rd>'

Now lets make simplest query:

SELECT @@version
     GO

You should see output like:

linuxdoc4

Now you can go ahead and start creating databases, tables, moving data, etc.

Hope this helps.
