You can create environment variables on a Linux Image Builder instance. Creating environment variables makes them available on streaming instances created from that image.
Note
On Linux fleet instances, environment variables set using the Image Assistant (GUI) tool and the default system environment variables are exported through the /etc/profile.d/appstream_system_vars.sh script. To access these environment variables, you must explicitly source the /etc/profile.d/appstream_system_vars.sh script in your applications.
To create environment variables for your users
-
If the folder
/etc/profiledoesn’t exist, run the following command to create it:[ImageBuilderAdmin]$ sudo mkdir -p /etc/profile.d
-
To create a new shell script file (for example, my-environment.sh) in this folder, run the following command:
[ImageBuilderAdmin]$ vim my-environment.sh
-
On first line of the script file, add the following content:
#!/bin/sh
-
For each subsequent line, add an export command to set the environment variables for your image. The following example adds
$HOME/binto thePATHvariable:export PATH=”$HOME/bin:$PATH”
-
Press the Esc key to return to command mode in vim, then run the following command to save your script and exit vim:
:x
-
Run the following command to allow the script to run as a program:
[ImageBuilderAdmin]$ chmod +x my-environment.sh
