Docker Hello

This is an example of using Docker. Look inside Dockerfile, it's based on the official nginx image.

Ensure that your PC have Docker installed.

Installation

1. Clone this repo

git clone [email protected]:yesnik/docker_hello.git

2. Bulid an image with the repo name docker_hello and tag 1.0

cd docker_hello
docker build -t docker_hello:1.0 .

3. Ensure that the image has been created

docker images

4. Create container based on our image

docker run --name docker_hello_container -d -p 8080:80 docker_hello:1.0

Params:

• --name docker_hello_container - name of the created container
• -d - detaches from the container, running it in the background
• -p 8080:80 - maps network ports. Your host's port 8080 will be mapped to container's 80 port

Play with the container

1. Look at the running containers

docker ps

2. Connect to the container and use bash

docker exec -it docker_hello_container bash

Flag -it attaches us to an interactive tty in the container.

docker stop docker_hello_container

docker rm docker_hello_container
