Here you can see that the sqlservr process is unable to open a file instance_id. docker stop sql1Ĭreate a new container pointing to that existing Data Volume (sqldata1), this time I’m not using -d so we can attach to stdout and see the error messages on the terminal. Now to start the process of upgrading from 2017 to 2019, we’ll stop and remove the existing container. Sqlcmd -S localhost,1433 -U sa -Q 'SELECT name from sys.databases' -P $PASSWORD -W sqlcmd -S localhost,1433 -U sa -Q 'CREATE DATABASE TestDB1' -P $PASSWORD Let’s create a database and confirm it’s there. e 'ACCEPT_EULA=Y' -e 'MSSQL_SA_PASSWORD='$PASSWORD \ This will create the files with root as the owner and group. Start up a container with a Data Volume (sqldata1) using the 2017 image. Let’s do it together… Start Up a Container with a Data Volume Once we adjust the permissions, stop that ubuntu container and start up SQL Server’s 2019 non-root container and everything should be happy happy. If you’re databases and log files are in other paths you’ll have to take that into account if using this process. The way I fixed this issue is by stopping the SQL Server 2017 container and using another container, attaching the data volumes used by the 2017 container into this container then recursively adjusting the permissions to allow a user with the uid 10001 access to the files in the instance directory /var/opt/mssql. This new user doesn’t have permission to open the database files and other files used by SQL Server. Now when we come along later and start up a 2019 container, the sqlservr process is running as the user msssql ( uid 10001 by default). Any files created by this process will have the user and group ownership of the root user. When you start up the 2017 container, the SQL Server ( sqlservr) process is running as root ( uid 0). If you’re using Linux container on Linux, you’ll adjust the file system permissions directly.

The scenario below is if you’re using a Linux based SQL Server container on Windows or Mac host where the container volumes are backed by a Docker Moby or HyperKit virtual machine. This article describe a solution to getting things sorted and running again. As you can see here, my friend Grant Fritchey came across this issue recently and asked for some help on Twitter’s #sqlhelp.

But what if you’re using a 2017 container running as root and want to upgrade your system the SQL Server 2019 container…well something’s going to break.

The following section explains how to use data volumes to persist your database files even if the associated containers are deleted.Recently Microsoft released a Non-Root SQL Server 2019 container and that’s the default if you’re pulling a new container image. However, if you remove the container with docker rm, everything in the container is deleted, including SQL Server and your databases. Your SQL Server configuration changes and database files are persisted in the container even if you restart the container with docker stop and docker start.
If you reversed the commands in the previous example, the container would shut down when the do-my-sql-commands.sh script completes. The following command illustrates this inside a Dockerfile: /usr/src/app/do-my-sql-commands.sh & /opt/mssql/bin/sqlservr All other commands are run in the background. For example, if you want to run a script and start SQL Server, make sure that the SQL Server process is the right-most command. If it exits, the container will shut down. If you do create your own Dockerfile, be aware of the foreground process, because this process controls the life of the container.
For more information, see a demo that combines SQL Server and a Node application. It is possible to create your own Dockerfile to create a customized SQL Server container. This article explains how you can configure and customize SQL Server Docker containers, such as persisting your data, moving files from and to containers, and changing default settings.
