tar -xzvf archive.tar.gz


Extract a tar.gz to a specific directory

Git initialise new repository with existing source

Image
If you have an existing folder with code you want to push (commit) into a new fresh git repository you need to first create the repository in GitHub or Bitbucket. You also need to have git installed on your local machine. To start off in the directory you have your existing code project git init Connect to a remote repository git remote add origin git@bitbucket.org:username/reponame.git Add files to the commit git add .

The Linux Filesystem

  / - The Root Directory System root /bin - User Binaries In single user mode this is where user apps such as firefox etc are stored /sbin is similar in that is is where administration binaries are stored. /boot - Static Boot Files GRUB, linux kernels are stored here, needed to be able to boot the system. Config for boot is stored in /etc /dev - Device Files Devices are exposed as files. Eg /dev/sda represents the first SATA drive. It also contains psuedo-devices. For example: /dev/random produces random numbers. /dev/null returns no output and discards all input. /etc - Configuration Files Contains systems wide configuration files. User specific config files live in each users /home/{user} folder /home - Home Folders User specific files and user specific configuration. /lib - Shared Libraries Contains essential libraries consumed by binaries in /bin and /sbin. /usr/lib contains libraries consumed by binaries in /usr/bin /lost+found Recovered Files On system crash, recovered file...

Docker introduction

Image
  Docker Image and Container concepts An image is typically a layered operating system file, such as Alpine Linux, which is a commonly used OS used with Docker. Images are downloaded. A container is a build of the image with a defined configuration. Containers are run. Docker Compose allows multiple containers to run. Dockerfile Dockerfile defines image to build, operating system, configuration. Note capital D. docker-compose.yml can orchestrate containers Dockertoolbox is legacy Getting started Install Docker Preferably on a Linux based system.  Ive had success on Debian, Windows WSL2 subsystem (Ubuntu), and Mac OS (Intel CPU).  Running natively on Windows I can't recommend.  Ive read that there is now support for M1 Macs too. Define the image to build Dockerfile example, pulls in another Dockerfile from hub.docker.com as a starting point, copies the source code from local into the VM, and opens port 80. # Use existing image from hub.docker.com as starting point ...
