Rebuilding a Virtualenv - Link to Original

If you need to rebuild your virtualenv following a system image upgrade

The instructions below will contain instructions for people who use plain virtualenv and virtualenvwrapper; make sure that you use the appropriate ones for the kind of virtualenv you're using. Use a Bash console to enter the commands.

1) Use a requirements.txt file to record what packages you're using

GNU Radio in M1 Macs (with Docker Desktop)

This note describes the steps we took with the SETI Institute summer interns 2021 to install GNU Radio in their M1 Macs (MacBook Air M1 2020 model). We used gnuradio-docker-env as a starting point, which was of invaluable help.

There might be omissions, typos, etc., in this note, so any feedback is welcome. The procedure could also be streamlined a lot by generating known-good images and pushing the to Docker Hub.

Reference Portainer Managing Docker Engine Remotely

This tutorial is about managing a Docker Engine remotely using Portainer connected to the protected Docker daemon socket (TCP port 2376). By default, you can manage Docker locally through a non-networked UNIX socket (option -v /var/run/docker.sock:/var/run/docker.sock while running Portainer). But, if you want the Docker Engine to be reachable through the network in a safe manner, you need to enable TLS by specifying the --tlsverify flag and pointing Docker’s --tlscacert flag to a CA certificate. Then, the daemon only accepts connections from clients that are authenticated by a certificate signed by that CA certificate.

This tutorial accomplishes the following:

Create a CA, server and client keys with OpenSSL,
Configure the remote API for dockerd (Docker Engine) to allow external connections,
Deploy Portainer and connect it to the protected Docker daemon socket.
