Mint下安裝Dockerhtml

sudo apt-get install lxc-dockerdocker

Docker啓動報錯：shell

須要安裝依賴包ubuntu

sudo apt-get install apparmorbash

運行Docker鏡像app

sudo docker run -i -t ubuntu /bin/bash日誌

-i：保證容器中STDIN開啓code

-t：爲容器分配一個僞tty終端orm

查看當前系統中容器的列表

docker ps -a

從新打開容器會話shell

sudo docker attach titus_docker_container

exit退出容器shell後，容器會隨之中止運行。若需從新運行容器，須要執行

sudo docker start titus_docker_container sudo docker attach titus_docker_container

建立守護式容器，不打開shell會話，讓進程打印hello world

huangyi@HP ~ % sudo docker run --name daemon_dave -d ubuntu /bin/sh -c "while true;do echo hello world; sleep 1; done"

查看daemon容器內部日誌

sudo docker logs daemon_dave

查看daemon容器內部進程

sudo docker top daemon_dave

sudo docker inspect daemon_dave

查看daemon容器固定字段信息

sudo docker inspect --format='{{ .NetworkSettings.IPAddress }}' daemon_dave
