صفحه‌ای جدید حاوی «<div dir="ltr"> O) Installing Docker on Ubuntu: $ sudo apt-get install -y docker.io $ sudo ln -sf /usr/bin/docker.io /usr/local/bin/doc...» ایجاد کرد

صفحهٔ تازه

<div dir="ltr">
O) Installing Docker on Ubuntu:

$ sudo apt-get install -y docker.io
$ sudo ln -sf /usr/bin/docker.io /usr/local/bin/docker
$ sudo sed -i '$acomplete -F _docker docker' /etc/bash_completion.d/docker.io

- Verify Installation:
$ sudo docker version

O) Docker Hub and Containers
- The Docker command:
Usage: [sudo] docker [flags] [command] [arguments]

- To list all the commands:
$ sudo docker

- To view the usage sample:
Usage: sudo docker [command]

- create an account from the command line:
$ sudo docker login

- Display Docker Images:
$ sudo docker images

- Searching images from Docker command line:
Search Syntax: Docker search [image name]

- Launching Docker containers:
$ sudo docker run ubuntu:14.04 /bin/echo â??Hello worldâ??

- Launch On Interactive Mode:
$ sudo docker run -t -i ubuntu:14.04 /bin/bash

- Creating a daemonized container:
$ sudo docker run -d ubuntu:14.04 /bin/sh â??c â??while true; do sleep 4; date; doneâ??
is running:
$ sudo docker ps
$ sudo docker ps -q
view logs output:
$ sudo docker logs [name]
$ sudo docker logs $(sudo docker ps -lq)
stop container:
$ sudo docker stop [name]

O) Connect Client To Remote Host:
On Docker Server:
$ sudo service docker.io stop
$ docker -H tcp://0.0.0.0:5000 -H unix:///var/run/docker.sock -d &
On Docker Client:
$ sudo docker -H 10.0.0.4:5000 ps
$ docker -H <host-ip>:5000 run -it â??name test-container ubuntu

O) Python web application container:
- Default Randomized Port Mapping:
$ sudo docker pull training/webapp
|
$ sudo docker run -d -P training/webapp pyhton app.py
$ sudo docker ps -l

knowing port data:
$ sudo docker port [name] 5000

- Stop/Restart Container
$ sudo docker stop [name]
$ sudo docker restart [name]

- Remove Container:
$ sudo docker stop [name] && sudo docker rm [name]
| force
$ sudo docker rm -f [name]

- Manual Port Mapping:
$ sudo docker run -d -p 5000:5000 training/webapp pyhton app.py

view logs of running container:
$ sudo docker logs -f [name]

view all proccess running inside:
$ sudo docker top [name]

- Inspect Container:
$ sudo docker inspect [name]
$ sudo docker inspect -f '{{.NetworkSettings.IPAddress}}' [name]

- Stop/Remove All:
$ sudo docker stop $(sudo docker ps -a -q)
$ sudo docker rm $(sudo docker ps -a -q)

O) Our own images:
- From preconfigured image:
$ sudo docker run -t -i [image] /bin/bash
Syntax: sudo docker commit -m=â??<your commit message hereâ?? -a=â??<maintainer name hereâ??\ <container id> <docker hub username>/<image name>:<tag>

Syntax: sudo docker run -t -i username/imagename:tag /bin/bash

- Dockerfile:
$ touch Dockerfile

-----------------------
FROM ubuntu:14.04
MAINTAINER payam naderi <naderi.payam@gmail.com>
RUN apt-get update && apt-get install -y ruby ruby-dev
RUN gem install sinatra
-----------------------

Built image:
$ sudo Docker build â??t=â??username/imagename:tagâ?? .
$ sudo docker run -t -i hcldevops/sinatra:v2 /bin/bash

- Image tagging:
$ sudo docker tag b7065749275a hcldevops/sinatra:devel

- Upload Image To Docker Hub:
$ sudo docker login
Sysntax: docker push <username>/<imagename>

- Removing images from Docker host:
$ sudo docker rmi training/sinatra
| remove all
$ docker rmi $(docker images -q)

O) Container Linking: (inside webapp)
- Port Mapping:
sudo docker run -d -P training/webapp python app.py
sudo docker run -d -p 5000:5000 training/webapp python app.py
sudo docker run -d -p 127.0.0.1:5000:5000 training/webapp python app.py
sudo docker run -d -p 127.0.0.1::5000 training/webapp python app.py
sudo docker run -d -p 127.0.0.1:5000:5000/udp training/webapp python app.py

- Linking containers together:
Naming Containers:
$ sudo docker run -d -P â??name web training/webapp python app.py
$ sudo docker ps â??l
|
$ sudo docker inspect -f â??{{ .Name }}â?? ae6bcece4532

Link Containers:
Syntax: â??link name:alias
$ sudo docker run -d â??name db training/postgres
$ sudo docker run -d -P â??name web â??link db:db training/webapp python app.py
$ sudo docker ps

How Linking Containers Work:
must be runned: $ sudo docker run -d â??name db training/postgres
$ sudo docker run â??rm â??name web2 â??link db:db training/webapp env
$ sudo docker run -t -i â??rm â??link db:db training/webapp /bin/bash
$ cat /etc/hosts
$ ping db

O) Data Management:
- Data Volume:
Adding data volumes to containers:
$ sudo docker run -d -P â??name web -v /webapp training/webapp python app.py

Data volumes from host directories:
-v /source-directory:/opt/directory
$ sudo docker run -d -P â??name web1 -v /src/webapp:/opt/webapp training/webapp python app.py

Creating read only data volume:
$ sudo docker run -d -P â??name web2 -v /src/webapp:/opt/webapp:ro training/webapp python app.py

Data volume from host file:
$ sudo docker run â??rm -it -v ~/.bash_history:/.bash_history ubuntu /bin/bash

- Data Container:
$ sudo docker run -d -v /dbdata â??name dbdata training/postgres echo data-only container for postgres
$ sudo docker run -d â??volumes-from dbdata â??name db1 training/postgres

$ sudo docker run -d â??name db2 â??volumes-from db1 training/postgres mount to same

$ sudo docker rm -v dbdata

- Backing up data volumes:
$ sudo docker run â??volumes-from dbdata -v $(pwd):/backup ubuntu tar cvf /backup/backup.tar /dbdata
