In the previous post, I talked about how to do the initial setup for Raspberry Pi. In this post, I will talk about the installation of the tools that are used most of the time in software development.
To put it briefly, Docker is a container technology that you can run an application in an isolated environment.
1-) Install Docker with snap
1sudo snap install dockerIf it is ok when you execute the following command
1sudo docker run hello-worldYou will see the following output
1Unable to find image 'hello-world:latest' locally2latest: Pulling from library/hello-world3256ab8fe8778: Pull complete4Digest: sha256:4cf9c47f86df71d48364001ede3a4fcd85ae80ce02ebad74156906caff5378bc5Status: Downloaded newer image for hello-world:latest67Hello from Docker!8This message shows that your installation appears to be working correctly.910To generate this message, Docker took the following steps:11 1. The Docker client contacted the Docker daemon.12 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.13 (arm64v8)14 3. The Docker daemon created a new container from that image which runs the15 executable that produces the output you are currently reading.16 4. The Docker daemon streamed that output to the Docker client, which sent it17 to your terminal.1819To try something more ambitious, you can run an Ubuntu container with:20 $ docker run -it ubuntu bash2122Share images, automate workflows, and more with a free Docker ID:23 https://hub.docker.com/2425For more examples and ideas, visit:26 https://docs.docker.com/get-started/2-) Create a group named docker to be able to use docker commands without sudo
1sudo groupadd docker3-) Add your user to the docker group
1sudo usermod -aG docker $USER4-) Reboot your system
1sudo reboot5-) If everything is ok you can able execute the following command without sudo
1docker run hello-world1-) Pull and run the latest MongoDB from Docker with the name mongo
1docker run -d -p 27017:27017 -v ~/mongo/data:/data/db --name mongo mongoWith the -v parameter MongoDB data become persistent to Raspberry Pi's ~/mongo/data directory. In this way, we don't lose any data when we delete containers.
You can visually explore the database with MongoDB Compass also, you can use the following URL format to connect to DB via Compass
1mongodb://YOUR_RPIs_LOCAL_IP:270172-) You can access the mongo shell directly via the following command
1docker exec -it mongo mongo1-) Install NVM (Node Version Manager)
1curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.36.0/install.sh | bashIt will generate the following output

1command -v nvmYou will see the following output

1nvm install --ltsYou will see an output like this
