An alias is a user-defined shortcut for a longer command or sequence of commands. It is essentially a custom nickname you can assign to a specific action or utility
Step 1: Check for Existing Aliases
Before creating a new alias, it’s essential to check if the alias ‘k’ is already in use or if it conflicts with any existing commands
alias | grep k=
Step 2: Edit Your Shell Configuration File
Aliases are usually defined in your shell’s configuration file, in case edit via vi
vi .bashrc
Step 3: Add the Alias
In your shell configuration file, add the following line
alias k='kubectl'
This line assigns the alias ‘k’ to the kubectl command
Step 4: Save and Apply the Changes
After adding the alias, save the changes and close the text editor
source .bashrc
Step 5: Test the Alias
Now that you have set up the alias
k get pods
If everything was configured correctly, the output should be the same as if you had typed kubectl get pods
