RHEL 8.x

To build a custom RHEL 8.x base image:

SSH into the system where App Workbench is installed.
Create a directory by executing the mkdir command, such as:
```
$> mkdir -p ~/src/base_images.
```
Switch to the directory you just created by executing the cd command, such as:
```
$> cd ~/src/base_images
```
.
Retrieve the BlueData base image for RHEL 7 by executing the following command:
```
$> bdwb --baseimg rhel7
```
.
This creates a directory called rhel8 under your current directory.

Switch to the rhel8 directory by executing the following command:

$> cd rhel8
        $> 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   79 Oct 10 08:59 template

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 set to 4.1.
- $> export UPSTREAM='<upstream>', where <upstream> is the name of the upstream image source, such as artifactory.com/enterprise:rhel8. The default upstream image source is rhel:rhel8.
NOTE This base image can only be built on a RHEL server.
Modify the base image as needed.
Make the new image by executing the following command:
```
$> make rhel8
```
Verify that the image has built successfully by executing the following command:
```
$> docker images
```
