#DOCKER RUN IMAGE COMMAND NETWORK APK#

(alpine uses apk for its package manager - can install bash if you want) NETWORKING 'bridge' or 'docker0' is the default network Get port $ docker container port (use sh because it does not include bash) Use exec to edit config, etc $ docker container exec -it mysql bashДЄlpine is a very small Linux distro good for docker $ docker container run -it alpine sh (no bash because ubuntu uses bash by default) You can also make it so when you exit the container does not stay by using the -rm flag $ docker container run -rm -it -name ubuntuДЄccess an already created container, start with -ai $ docker container start -ai ubuntu Run/Create Ubuntu container $ docker container run -it -name ubuntu ubuntu

i = interactive Keep STDIN open if not attachedДЇor Git Bash, use 'winpty' $ winpty docker container run -it -name nginx bash.

Performance stats (cpu, mem, network, disk, etc) $ docker container stats ДЄCCESSING CONTAINERS Create new nginx container and bash into $ docker container run -it -name nginx bash Specific property (-format) $ docker container inspect -format ''

MYSQL: $ docker container run -d -p 3306:3306 -name mysql -env MYSQL_ROOT_PASSWORD=123456 mysqlД¬ONTAINER INFO View info on container $ docker container inspect MONGODB: $ docker container run -d -p 27017:27017 -name mongo mongo NGINX: $ docker container run -d -p 80:80 -name nginx nginx (-p 80:80 is optional as it runs on 80 by default)ДЄPACHE: $ docker container run -d -p 8080:80 -name apache httpd Host provides the kernel, big difference between VM.

#DOCKER RUN IMAGE COMMAND NETWORK HOW TO#

Images are app bianaries and dependencies with meta data about the image data and how to run the image.Remove all images $ docker rmi $(docker images -a -q) We can also just pull down images $ docker pull On Linux however you can run 'ps aux' and see the processes directly IMAGE COMMANDS List the images we have pulled $ docker image ls In Windows/Mac, Docker runs in a mini-VM so to see the processes youll need to connect directly to that. List processes running in container $ docker container top Дocker containers are often compared to virtual machines but they are actually just processes running on your host os. Get logs (Use name or ID) $ docker container logs Remove all containers $ docker rm $(docker ps -aq) Remove multiple containers $ docker container rm To remove a running container use force(-f) $ docker container rm -f Remove container (Can not remove running containers, must stop first) $ docker container rm Stop all running containers $ docker stop $(docker ps -aq) List all containers (Even if not running) $ docker container ls -a List running containers $ docker container ls We can specify versions like 'nginx:1.09'.We could do '$ docker container run -publish 8000:80 -detach nginx' to use port 8000.

We specified to take port 80- on the host and forward to port 80 on the container.

Pulled it down (latest version), stored in the image cache.

If not found in cache, it looks to the default image repo on Dockerhub.

Looked for image called nginx in image cache.

Naming Containers $ docker container run -d -p 80:80 -name nginx-server nginx Shorthand $ docker container run -d -p 80:80 nginx WORKING WITH CONTAINERS Create an run a container in foreground $ docker container run -it -p 80:80 nginxД¬reate an run a container in background $ docker container run -d -p 80:80 nginx Show info like number of containers, etc $ docker info This may be helpful for debugging your builds, or modifying the Docker or VM filesystem configuration.Docker Commands, Help & Tips Show commands & management commands $ docker When a remote Docker environment is spun up, an SSH alias is created for you so you can SSH into the remote Docker virtual machine. # Populate bundler-data container from circleci cache - restore_cache : keys : - v4-bundler-cache- paths : - ~/bundler-cache Accessing the remote docker environment
