Docker Commands

Docker Network: Connects a running container to a network. If the network Id started with "8ac", which command would you use?

• >docker network create swfnetwork

• docker network connect swfnetwork 8ac

• > docker network connect my_bridge_network container1

• docker network rm swfnetwork

What does the command '>docker network ls' do?

• A) Docker Network: Creates a new Docker network.

• B) Docker: List only running containers

• C) Docker Network: Lists Docker networks.

• D) Docker: List IDs of final Docker images available locally

Docker: Create a new image 'my_new_image' from 'my_container' with a custom message and author. Which command would you use?

• > docker build -m "Added custom message" -a "John Wick" my_container my_new_image

• > docker create -m "Added custom message" -a "John Wick" my_container my_new_image

• > docker push -m "Added custom message" -a "John Wick" my_container my_new_image

• > docker commit -m "Added custom message" -a "John Wick" my_container my_new_image

Docker: Connect an already running container named "container1" to the bridge network named "my_bridge_network".

• > docker network disconnect my_bridge_network container1

• > docker network remove my_bridge_network container1

• > docker network connect my_bridge_network container1

• > docker network create my_bridge_network container1

Docker: Search Docker Hub for all available "nginx" images.

• > docker run -d --name secure_session --tmpfs home/data/sessions nginx

• > docker create -p 6000:6379 nginx

• > docker run -v /html:/usr/share/nginx/html nginx

• > docker search nginx

Docker: Create and start a MySQL container named "database" in detached mode.

• > docker run -d --name database mysql

• > docker create -d --name database mysql

• > docker start -d --name database mysql

• > docker run -d --name database postgres

Docker: Create and run a container from the 'my_web_app' image on the network 'my_bridge_network' with port 8080 on the host mapped to port 80 in the container.

• > docker run -v /html:/usr/share/nginx/html nginx

• > docker run -d -p 8080:80 --name webserver nginx

• > docker run -p 8080:80 --network my_bridge_network my_web_app

• > docker run --name container1 --network my_bridge_network nginx

Dockerfile: Execute commands in a new layer on top of the current image.

• RUN

• START

• COPY

• ADD

Docker: List only the IDs of all containers.

• > docker ps -a -q

• > docker ps -all -quiet

• > docker stop container1 container2 container3

• > docker ps

• > docker ps -a

Dockerfile: Provide default command to execute when the container starts.

• MMC

• CLI

• CMD

• PPID
