Docker Hub

Docker Hub allows you to share and save your custom images and load a library of existing images. Link

How To Install and Use Docker on Ubuntu 20.04 

Docker is an application that simplifies the process of managing application processes in containers. Containers let you run your applications in resource-isolated processes. They're similar to virtual machines, but containers are more portable, more resource-friendly, and more dependent on the host operating system. Link.

Pi 400 Docker

I tried getting docker up and running also on the pi400 but as its arm based i came across some issues running normal docker containers, assuming this is due to the images being intel or amd based. 

Local domain

To create a .local domain, install Avahi Daemon on your Pi;

sudo apt-get install avahi-daemon

By default, the hostname is raspberrypi.

Install Docker-Compose on Raspberry Pi - JFrog Connect (formerly Upswift)

Docker containers are light-weight, requires minimal resources and makes it possible to deliver your software quicker, which makes them extremely useful for SBC's such as Raspberry Pi. How do we define and run multi-container docker applications? Docker-Compose is the answer. Link.

 

Install Docker on Rasberry Pi

install docker

curl -fsSL https://get.docker.com -o get-docker.sh

sudo sh get-docker.sh

‍sudo usermod -aG docker ${USER}

check if its in the group

groups ${USER}

su the user or logout and back in

test if docker is working

docker version

‍docker info

docker run hello-world

docker image rm hello-world

Docker Compose on pi400

sudo apt-get install libffi-dev libssl-dev
sudo apt install python3-dev
sudo apt-get install -y python3 python3-pip

‍sudo pip3 install docker-compose

‍sudo systemctl to enable Docker??

sudo apt update

sudo apt install apt-transport-https ca-certificates curl software-properties-common

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu focal stable"

Status: Downloaded newer image for hello-world:latest

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

Share images, automate workflows, and more with a free Docker ID:
 https://hub.docker.com/

For more examples and ideas, visit:
 https://docs.docker.com/get-started/

docker search ubuntu

docker pull ubuntu

show images
docker images
docker run ubuntu

run ubuntu image with an interactive shell

docker run -it ubuntu

install node on this new instance of ubuntu

copy the instance id as well

docker run -it ubuntu

#007f6db6d204

apt update

apt install nodejs

node -v

#Any changes you make inside the container only apply to that container.

show all containers
docker ps -a
docker ps -l

#start a container by id
docker start 007f6db6d204
docker run -it sleepy_wiles
docker run -it 007f6db6d204

commit changes to image

requires a docker hub user id

docker commit -m "What you did to the image" -a "Author Name" container_id repository/new_image_name

docker commit -m "added Node.js" -a "sammy" d9b100f2f636 sammy/ubuntu-nodejs

enable docker auto start on restart of the vm

$ sudo systemctl enable docker

install docker compose

apt install docker-compose

get a basic lamp stack running on docker with local php files

mkdir $HOME/apache && cd $HOME/apache

printf '<?php phpinfo(); ?>' > info.php

docker run -d --name=apache -p 8085:80 -v $HOME/apache:/var/www/html php:apache

test it.

nerd2.kruxor.com:8085

running but getting error

stop and delete the image

$ docker stop apache
$ docker rm apache

install and run wordpress...

this will create a wordpress and mysql containers and wordpress.

do a test install of wordpress and sqlserver... from here:

https://blog.ssdnodes.com/blog/getting-started-docker-vps/

mkdir wp_test && cd wp_test

nano docker-compose.yml

services:

     volumes:

volumes:
    db_data:


docker-compose up -d

docker ps

test:
http://nerd2.kruxor.com:8085

to save the data and shut down
docker-compose down

then need to figure out how to route nginx to the different docker containers, i guess just run them on diff ports like this:

docker run -d --name=apache -p 8085:80 -v $HOME/apache:/var/www/html php:apache

copy core files to git private and

or just zip them up and then download with curl or wget

leave the git part for another time

copy kruxor.com

tar gz something

tar -czvf ~/backup/$1.tar.gz /var/www/html/$1/

tar -czvf ~/kruxor.tar.gz /var/www/html/kruxor.com/

this one should work once the virtual and lets encrypt hosts are set.

Dockerise your PHP application with Nginx and PHP7-FPM

Before we start, we have to agree on one thing - Docker is super cool! If you are not familiar with Docker, I suggest to have a look at the tons of "Getting starting with Docker" or "What is Docker?" articles and then come back here.
