CentOS 7.x

To build a custom CentOS 7.x base image:

  1. SSH into the system where App Workbench is installed.

  2. Create a directory by executing the mkdir command, such as:

    $> mkdir -p ~/src/base_images.

  3. Switch to the directory you just created by executing the cd command, such as:

    $> cd ~/src/base_images
    .

  4. Retrieve the BlueData base image for CentOS 7 by executing the following command:

    $> bdwb --baseimg centos7
    .

    This creates a directory called centos7 under your current directory.

  5. Switch to the centos7 directory by executing the following command:

    $> cd centos7
        $> ls -a
    You should see the following: 
                            drwxr-xr-x. 3 root root   54 Oct 10 08:59 .
                        drwxr-xr-x. 7 root root   78 Oct 15 12:32 ..
                        -rw-r--r--. 1 root root 4361 Oct  9 15:36 build.sh
                        -rw-r--r--. 1 root root 1393 Oct  9 15:36 Makefile
                        drwxr-xr-x. 3 root root  121 Oct 15 14:32 template
  6. You may override one or more of the following parameter(s) by executing the following command(s), as appropriate:
    • $> export BASE_IMG_ORGNAME='<orgname>', where <orgname> is the name of your organization, such as enterprise. The default name is bluedata.
    • $> export BASE_IMG_VERSION='<version>', where <version> is the image version number, such as 1.0. The default version is 4.1.
    • $> export UPSTREAM='<upstream>', where <upstream> is the name of the upstream image source, such as artifactory.com/enterprise:centos7. The default upstream image source is centos:centos7.
  7. Modify the base image as needed.

  8. Make the new image by executing the following command:

    $> make centos7

  9. Verify that the image has built successfully by executing the following command:

    $> docker images
    .
