Common Docker CLI
Docker Run - runs processes in isolated container option
| Option | Description | Note |
| -d | runs the container in the background | |
| -it | For interactive processes ( like a shell). |
|
| --name | Container identification | |
| -p | export port <host port>:<internal port> | 80:3000 |
| exec | run a command in a running container |
|
| -v | volume ( shared filesystems ) e.g. -v [host-src]:[container-dest]:[option] |
-v /run/udev:/run/udev:ro, -v $PWD:/home/adv:rw |
| --privileged |
Docker will enable access to all devices on the host as well as set some configuration in AppArmor or SELinux to allow the container nearly all the same access to the host as processes running outside containers on the host |
|
Start a docker container and export server port
$sudo docker run -d -it --name advigw-mqtt-bus -p 1883:1883 advigw4x86/mqtt-bus $sudo docker run -d -it --name advigw-api-gw -p 3000:3000 advigw4x86/api-gw
Start a docker container and enter into bash
// need add -it // Run and enter to bash $sudo docker run -d -it --name advigw-wisesnail-lib-dev -v $PWD:/home/adv/workspace:rw advigw4x86/wisesnail-lib /bin/bash // Enter a running container bash $sudo docker exec -it advigw-wisesnail-lib-dev bash
Stop / Start Docker Container
$sudo docker stop advigw-wsn-simulator $sudo docker start advigw-wsn-simulator
Docker logs : redictor stdout
// dcoker logs container-name > log.txt $docker logs advigw-wsn-simulator > log.txt // docker logs --follow container-name $docker logs --follow advigw-wsn-simulator
Check Network of Container
$docker inspect <CONTAINER ID/NAME> | grep -w "IPAddress" | awk '{ print $2 }' | head -n 1 | cut -d "," -f1
