Docker Services

sudo systemctl start docker
sudo systemctl stop docker
sudo systemctl restart docker
sudo systemctl status docker

Docker Command

docker pull [name]:[tag] default tag to latest

docker ps or docker container ls list of currently container process

Tutorial

Docker Build

docker build -t [tag name] -f [dockerfile] . : harus ada titik dibelakang karena parameter terakhir adalah path

Docker Run

-docker ps -a or docker container ps -a - docker container ps -a | grep my-ubuntu-container -docker container inspect my-ubuntu-container`

docker start [container] or docker stop [container]
docker run -it [image] --name [name] -d
- -it, --interactive and --tty agar menampilkan shell
- --rm agar ketika di-exit, maka container-nya otomatis di remove
- --name untuk memberikan nama
- -d detach untuk mengirimkan ke background
docker run -d --name=[container name] --mount source=[src-dir],destination=[dest-dir],readonly [image], contoh

docker run -d \
  --name=cratetest \
  --mount source=nginx-vol,destination=/usr/share/nginx/html,readonly \
  crate:latest

docker run -v $(pwd):$(pwd) -w $(pwd) -i -t ubuntu pwd , untuk mount-bind volume
docker run --read-only -v $(pwd):$(pwd) -w $(pwd) -i -t ubuntu pwd , untuk read only mount-bind volume
docker rm [container]
docker start [container] untuk memulai container
docker attach [container] untuk menampilkan di sheell saat ini
docker cp [container]:[path in container] [path in host] untuk copy dari container ke host
docker cp [path in host] [container]:[path in container] untuk copy file dari host ke container

Docker Compose

docker compose up -d
docker compose down

Docker Logs

docker info --format '{{.LoggingDriver}}' default log driver
docker inspect -f '{{.HostConfig.LogConfig.Type}}' [CONTAINER] untuk melihat log driver di container
docker run -it --log-driver none alpine ash run contyainer with no logs
docker run -dit --label production_status=testing -e os=ubuntu alpine sh run container with logs label production_status = testing

docker run \
      --log-driver local --log-opt max-size=10m \
      alpine echo hello world

Docker Installation

Install

ref: https://docs.docker.com/engine/install/ubuntu/

uninstall conflicting package for pkg in docker.io docker-doc docker-compose docker-compose-v2 podman-docker containerd runc; do sudo apt-get remove $pkg; done
Set up Docker's apt repository.

# Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

# Add the repository to Apt sources:
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
  $(. /etc/os-release && echo "${UBUNTU_CODENAME:-$VERSION_CODENAME}") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update

# install the latest version
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

To install the latest version, run:

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

Verify that the installation is successful by running the hello-world image. You have now successfully installed and started Docker Engine.

sudo docker run hello-world

Manage Docker as non-root user ref: https://docs.docker.com/engine/install/linux-postinstall/

sudo groupadd docker
sudo usermod -aG docker $USER
newgrp docker

# test docker run without sudo
docker run hello-world

Manage Docker Log Rotation

ref: https://docs.docker.com/engine/logging/drivers/json-file/

vi /etc/docker/daemon.json

{
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "10m",
    "max-file": "3"
  }
}

sudo systemctl restart docker
