## Install Docker on Ubuntu:
#1
```
sudo su
sudo apt update
```
#2
```
sudo apt install apt-transport-https ca-certificates curl software-properties-common
```
#3
```
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
```
#4
```
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
```
#5
```
sudo apt update
```
#6
```
apt-cache policy docker-ce
```
#7
```
sudo apt install docker-ce
```
#8
```
sudo systemctl status docker
```
##
## ENABLE Docker API
1. Open docker.service file:
```
vi /lib/systemd/system/docker.service
```
2. Find the line starting with ExecStart and replace with this:
```
ExecStart=/usr/bin/dockerd -H fd:// -H tcp://0.0.0.0:4243 --containerd=/run/containerd/containerd.sock
```
Save the Modified File
3. Reload the docker daemon using the below command
```
systemctl daemon-reload
```
4. Restart the docker service using the below command
```
sudo service docker restart
```
5. Confirm docker is successfully restarted
```
sudo systemctl status docker
```
You should see the following terminal output:
```
● docker.service - Docker Application Container Engine
Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)
Active: active (running) since Fri 2023-10-27 19:34:11 CEST; 2s ago
TriggeredBy: ● docker.socket
Docs: https://docs.docker.com
Main PID: 27335 (dockerd)
Tasks: 18
Memory: 24.9M
CPU: 553ms
CGroup: /system.slice/docker.service
└─27335 /usr/bin/dockerd -H fd:// -H=tcp://0.0.0.0:4243 --containerd=/run/containerd/containerd.sock
```
6. Test if it is working by using this command, if everything is fine below command should return an empty array.
```
curl http://localhost:4243/images/json
```
To test a remote host, replace "localhost" with the public IP address of Docker Host.
Make sure to block port 4243 from unauthorized access.

## COMMANDS CHEATSHEET
TO SEND ANY API COMMAND TO A REMOTE DOCKER HOST JUST ADD THE HOST PARAMETER AFTER "docker" BEFORE THE ACTION:
```
docker -H "ipaddressofhost:4243" build . -t nameyourimage
```
BUILD DOCKERFILE IMAGE AND DEPLOY CONTAINER :
Navigate to the folder containing your dockerfile and execute.
```
cd folderxyz
docker build . -t nameyourimage
docker run --name nameyourcontainer -p 8084:8084 -d nameofimage
```
CREATE DOCKER NETWORK (BRIDGE MODE):
```
docker network create -d bridge nameofnetwork --subnet=172.75.0.0/16
```
IF YOU WANT TO DEPLOY A CONTAINER BUT ATTACH TO A DIFFERENT NETWORK:
```
docker run --net nameofnetwork --name nameyourcontainer -p 8084:8084 -d nameofimage
```
STOP RUNNING CONTAINER
```
docker container stop nameofcontainer
```
START RUNNING CONTAINER
```
docker container start nameofcontainer
```
SHOW THE LAST 30 LINES OF A CONTAINER CONSOLE LOG
```
docker logs --tail 30 nameofcontainer
```
SHOW MORE INFO ON A CONTAINER UP STATUS IN JSON FORMAT
```
docker container ls -f name=nameofcontainer --format json
```
DELETE CONTAINER
```
docker rm nameofcontainer
```
DELETE IMAGE
```
docker rmi nameofimage
```
