on Ubuntu 14.04:
-------------- docker service itself
-------------- install
------------- Main
- "ls /etc/*release" to know the container OS.
- remove all containers and clear cache (do not remove images...):
-- docker rm $(docker ps -a -q) && docker ps -a | cut -c-12 | xargs docker rm
.
.
-------------- docker service itself
service docker start
-------------- install
sudo bash
vi /etc/apt/sources.list.d/docker.list
deb https://apt.dockerproject.org/repo ubuntu-trusty main
apt-get update
you may have to do this with the associated keys if the former doesn't work
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys F76221572C52609D
apt-get -y install docker.io
apt-get install docker-engine
(don't do "apt-get install docker")
ln -sf /usr/bin/docker /usr/local/bin/docker
sed -i '$acomplete -F _docker docker' /etc/bash_completion.d/docker.io
or
sed -i '$acomplete -F _docker docker' /etc/bash_completion.d/docker
(depends which works)
- start docker daemon
- $ sudo service docker start
docker -v (should be at least 1.12)
docker version
docker info
docker pull hello-world
docker run -i -t hello-world
docker pull centos:6.6
docker run -i -t centos:6.6 /bin/bash
sudo docker images -a
------------- Main
- Run but exits right away with an error. Still, creates a container.
- docker run ubuntu
- Run and keeps an interactive session
- docker run -it ubuntu /bin/bash
- docker run -it alpine /bin/sh
- sudo docker run -i -t {repository_name}:{tag} /bin/bash
- Execute in a running container:
- “docker exec -i -t 7b33f4ed03a7 /bin/bash”
- sudo docker exec -i -t $(sudo docker ps -l -q) env
- Restart an existing container to continue working in it
- docker start 912ccdad8380
- then docker exec -it 912ccdad8380 /bin/bash
- To build a container from a Dockerfile:
- sudo docker build {Dockerfile_path}
-------------
docker rename 7d8b244480a2 my_django____4 (rename a container)
docker commit 7d8b244480a2 bob/hello_django:version2 (commit a new image from a running container)
docker save -o /home/bob/bob-hello-django-version4.tar bob/hello_django:version2
docker load -i bob-hello-django-version2.tar
-------------
- remove all containers and clear cache (do not remove images...):
-- docker rm $(docker ps -a -q) && docker ps -a | cut -c-12 | xargs docker rm
- remove a specific image
- sudo docker rmi -f 4f8eceb5cb78
- ignore container entrypoint:
- docker run -it --entrypoint=/bin/bash michal/hello_django_srp:version5
------------- problem 1
Docker version 1.6.2, build 7c8fca2
> docker save -o /tmp/docker1.tar michal/hello_django_srp:version6
FATA[0000] Error response from daemon: could not find image: no such id: michal/hello_django_srp:version6
--> there are two spaces before "michal" and docker is not robust to this
------------- static IP address
docker network create --subnet=172.18.0.0/16 mynet18 docker run --net mynet18 --ip 172.18.0.22 -it ubuntu:14.04 bash------------- bind volume mount (you need data from the host machine)
docker run -it -v /home/lee/tmp/docker-bind:/opt/container-path bob/solr_6_6:v7
otherwise, you can simply copy from the host to the container:
docker cp ./syn_acc.txt dfccf5a493c3:/usr/share/elasticsearch/config/resources/v1_02/
------------- other commands
docker inspect 7832d56ddf56docker run -it -p 8580:8080 bob/my-jetty:v1 (port matching)
