Prerequisites for setting up containerized developer toolkit on Linux

Ensure that you complete these prerequisite tasks before you set up developer toolkit on a Linux environment.

Procedure

  1. Install Docker version 18.x or later.
    For more information about installing Docker on Linux, see Install Docker CE and Orientation and setup.
    Note:
    • You must set up the developer toolkit environment on a Linux®-based environment as a nonroot user. To add the user to the docker group, see Manage Docker as a non-root user.
    • Do not use a root user or set up the developer toolkit environment in the /root directory.
    After installation, ensure that you start Docker and verify that Docker is installed correctly.
  2. Install Docker Compose version 2.x (tested on 2.23.0, 2.24 versions). For more information about installing Docker Compose, see Overview of Docker Compose and Install Docker Compose.
  3. It is recommended that you either stop or disable any native DB2®, WebSphere Application Server, Liberty, or MQ application services that are running locally. These services might unnecessarily consume system resources and the port numbers might conflict with the Docker Compose environment.
  4. On the host machine, add mqserver as a localhost in your /etc/hosts file.
