Needing PowerShell in Parrot Linux container
With my previous blog post about Getting PowerShell in Kali Linux container, I will be demonstrating on how you can install PowerShell 6 in Parrot (ParrotSec, Parrot GNU/Linux) distro container today.
In this demonstration, I will not be providing a break down of the processes in
the Dockerfile with explaination on each command execution except including
comments in the Dockerfile to indicate what it is doing.
For container newbies:
I will highly recommends you to read my previous blog post here to get a good understanding of each break down, since those steps will be some how similar.
Introducing PowerShell to Parrot container
In this section, I will provide a Dockerfile text document file that contains
all the commands to build a Parrot container and install PowerShell to the
Parrot Linux distro when you use DockerCLI docker build command.

Creating the Dockerfile
Firstly, create a new Dockerfile text document file.
Next, copy the code below and paste it into that Dockerfile text document
file.
Remember to save the Dockerfile file and exit from your editor.

Building from the Dockerfile
Now, you will have to use the DockerCLI docker build command to build the
Parrot container from the instructions in the Dockerfile text document file.

# Change to your working directory
cd \The\directory\where\your\Dockerfile\is\saved
# Build the container with the Dockerfile
docker build -t parrot .

Conclusion
Once the container build has completed, you can use the DockerCLI docker run
command to fire it up and have a play with it in PowerShell.
1
docker run --rm --interactive parrot
If you requires to run the container in bash, you can do it on the same
container with the command below.
1
docker run --rm --interactive --tty parrot bin/bash
And if you need to go back into PowerShell from the bash in the container,
type pwsh to switch into PowerShell.
There you go for those parrot folks out there.
