==설치==

===스크립트를 통한 설치===
https://docs.docker.com/install/linux/docker-ce/#install-using-the-convenience-script

 $ sudo wget -qO- <nowiki>https://get.docker.com/</nowiki> | sh

==== arch계열에서 package manager를 통한 설치====
 $ sudo pacman -S docker

===사용자 권한 추가===
 $ sudo usermod -aG docker $USER
다시 접속한 후에 적용된다.

==commit==
 $ docker commit CONTAINER IMAGE_NAME
==save==
 $ sudo docker save -o [파일명].tar 이미지명

==load==
 $ docker load < [파일명].tar

==run==
 $ docker run [OPTIONS] IMAGE [COMMAND] [ARG...]

=== Options ===
-v, --volume list                    Bind mount a volume

--volume-driver string           Optional volume driver for the container

--volumes-from list              Mount volumes from the specified container(s)

==== Network Settings ====
참고: https://docs.docker.com/engine/tutorials/networkingcontainers/<syntaxhighlight>
--dns=[]           : Set custom dns servers for the container
--network="bridge" : Connect a container to a network
                      'bridge': create a network stack on the default Docker bridge
                      'none': no networking
                      'container:<name|id>': reuse another container's network stack
                      'host': use the Docker host network stack
                      '<network-name>|<network-id>': connect to a user-defined network
--network-alias=[] : Add network-scoped alias for the container
--add-host=""      : Add a line to /etc/hosts (host:IP)
--mac-address=""   : Sets the container's Ethernet device's MAC address
--ip=""            : Sets the container's Ethernet device's IPv4 address
--ip6=""           : Sets the container's Ethernet device's IPv6 address
--link-local-ip=[] : Sets one or more container's Ethernet device's link local IPv4/IPv6 addresses

!Description
|-
|'''none'''
|No networking in the container.
|-
|'''bridge''' (default)
|Connect the container to the bridge via veth interfaces.
|-
|'''host'''
|Use the host's network stack inside the container.
|-
|'''container'''<nowiki>:<name|id></nowiki>
|Use the network stack of another container, specified via its ''name'' or ''id''.
|-
|'''NETWORK'''
|Connects the container to a user created network (using <code>docker network create</code> command)
|}
주의: <code>--network="host"</code> gives the container full access to local system services such as D-bus and is therefore considered insecure.

=== 예시 ===
 $ docker run -it -e LC_ALL=C.UTF-8 ubuntu bash
한글입력을 위해서 로케일을 변경할 수 있다.
 $ docker run -it --entrypoint bash ubuntu
--entrypoint string              Overwrite the default ENTRYPOINT of the image

==attach==
Attach local standard input, output, and error streams to a running container
 $ sudo docker attach [컨테이너명]
종료시에는 ctrl+p, ctrl+q로 나가야 컨테이너가 종료되지 않는다.

==exec==
컨테이너 명령실행
 $ sudo docker exec [컨테이너명] [명령어]

====옵션====
--user [사용자명]

==build==
The <code>docker build</code> command builds Docker images from a Dockerfile and a “context”. A build’s context is the set of files located in the specified <code>PATH</code> or <code>URL</code>.
 $  docker build [OPTIONS] PATH | URL | -
[[Dockerfile]]

-t, --tag list                Name and optionally a tag in the 'name:tag' format

-f                             Specify a Dockerfile

== builder ==
Manage builds.

=== prune ===
Remove build cache
 $ docker builder prune

== buildx ==
Extended build capabilities with BuildKit

=== ls ===
List builder instances
 $ docker buildx ls

=== create ===
Create a new builder instance
 $ docker buildx create [OPTIONS] [CONTEXT|ENDPOINT]
options

--use    Set the current builder instance

=== inspect ===
Inspect current builder instance
 $ docker buildx inspect [NAME]
options

--bootstrap    Ensure builder has booted before inspecting

=== rm ===
Remove a builder instance
 $ docker buildx rm [NAME]

== checkpoint ==
 $ docker checkpoint create

 $ docker checkpoint ls [컨테이너]

 $ docker checkpoint rm

==cp==
 $ docker cp [container name]:[container 내부 경로] [host 파일경로]

== volume ==
도커는 하나의 이미지로부터 여러 컨테이너를 만들기 위해서 '''Union File system'''을 사용한다. 유니온 파일 시스템은 원본 이미지에 변경된 내용(diff)를 추가하는 방식이므로, 다른 컨테이너에서 사용 할 수 없다. 애플리케이션에 따라서는 데이터를 다른 컨테이너와 공유 하거나 혹은 호스트에서 접근 할 수 있어야 하는 경우가 있는데, 이때 데이터 볼륨을 사용한다.

=== prune ===
Remove all unused local volumes
 $ docker volume prune

== network ==

=== ls ===
 $ docker network ls [OPTIONS]

== system ==
Usage:  docker system COMMAND

Manage Docker

Commands:

df          Show docker disk usage

events      Get real time events from the server

info        Display system-wide information

prune       Remove unused data

=== prune ===
도커를 사용하다보면 더이상 사용하지 않는 컨테이너와 이미지들이 저장공간을 필요없이 차지하게 된다. 이런 데이터들을 한 번에 정리할 수 있는 명령어.
 $ docker system prune --all --force

=== df ===
볼륨 크기를 볼 수 있어 디스크 정리할 때 사용할 수 있다.
