Logging into the Docker Hub gives you access to pre-defined Docker images, including Db2. Click on the Apply & Restart button and move on to the next step. Then, back in the Docker Desktop Preferences, add the new directory to the File Sharing list.

This will be quick, go ahead and open a Terminal window and create that (and a few other) directories. My preferred location is ~/Docker which expands to /Users/johnmaenpaa/Docker.

I remove the default locations and add a new one. I want to keep Docker contained to specific locations. My system has 8 cores and 32GB, so I let Docker use up to half the cores and 8GB of memory.īy default, Docker Desktop gives shared access to much of your macOS filesystem. You'll want Docker to use only a subset of your system's resources, but you also want to make sure to allocate enough memory to run Db2 with decent performance. The default general settings are probably fine but there are resource settings we likely need to change. Open the Docker Desktop Preferences and you'll get a window with a couple of tab-like sections. Ok, now that you have Docker Desktop up and running you can adjust some of its settings. After that, the Docker Desktop whale icon will live in the upper right menu bar.

To start it, double-click the icon from the Applications folder and provide your administrator password if asked. You download the Docker Desktop disk image, open it, and drag the icon into the Applications folder. Installing Docker Desktop on macOS if pretty straightforward. You need the Docker ID to log into the Docker Hub and pull images. Of course, this would also allow you to create your own images and share them. Go ahead and create a Docker ID while you are there and set up Two Factor Authentication to keep your access secure. If you have not already installed the macOS Docker Desktop application, go to and get started. That will be more than enough for my development needs. I hope we will be able to manage something similar on the upcoming Apple Silicon based computers.Īccording to the IBM Knowledge Center documentation here the Db2 Community Edition Docker image has the following, preset limitations: This will only work on the current line of Intel-based Apple computers. I’m using a modified version of the instructions for macOS found here. IBM has thoughtfully provided a Db2 image on Docker Hub and they documented the use of Docker for installation of Db2 Community Edition in the IBM Knowledge Center. It also means we can use a Linux distribution of Db2. This makes it fairly simple to run any Linux application, program, or server process in its own container within the desktop environment. On macOS, Docker uses a Linux-based container. Let's start with getting macOS Docker Desktop set up and get Db2 running on it.

I plan to go a bit further and get this usable for development on macOS, but that seems ambitious, so I had better break it down into multiple articles. Ian Bjorhovde wrote an excellent article for IDUG members. This is not the first article to cover Db2 on Docker, of course.

In this article, I'll go into how to set up and use Db2 using Docker on macOS. With the upsurge of virtualization tools, it has become much easier to work with Db2 on macOS. So, even when I could run a native Db2 server on my machine, I still ended up maintaining a Linux instance as well.

There was a brief period in 2009 when IBM provided a macOS implementation of Db2 Express-C v9.7 on Mac OS X, but many of the tools were not included and running a back-level version doesn't do much good over time. I have been using Apple computers as my primary platform for many years.įor most of those years, I had to maintain Linux/Windows virtual machines (using VMWare Fusion) in order to do much. The first step is installing Db2 using Docker.

The plan is to get the environment set up first, then some tools, and finally programming.

This is the first of a series of articles focused on setting up an Apple computer as a development environment for Db2 databases.
