$docker container run -d -p 8082:80  nginx:1.15.5-alpine
$docker container run -d -p 8083:80  nginx:1.15.5-alpine

Working with Images

• Save image from container and push your image to registry (Docker Hub)
• Create image from Dockerfile (basic)

Create new image from container

1. Create new container
$docker container run -d -p 8081:80  nginx:1.15.5-alpine

2. Execute to container and change data in file /usr/share/nginx/html/index.html
$docker container exec -it c0fb49c7b95c sh
#/exit

3. See diff in container
$docker container diff c0fb49c7b95c

4. Save container to new image
$docker container commit c0fb49c7b95c myweb:0.1

5. Try to create new container from new image
$docker container run -d -p 8082:80 myweb:0.1

Push new image to Registry (Docker Hub)

1. Login to Docker Hub
$docker login

2. Copy new image to correctly image name of Docker Hub
$docker image tag myweb:0.1 <your docker hub name>/myweb:0.1
$docker image tag myweb:0.1 somkiat/myweb:0.1

3. Push your image to Docker Hub
$docker image push somkiat/myweb:0.1

Create image from Dockerfile (basic)

1. Create Dockerfile
$touch Dockerfile

FROM nginx:1.15.5-alpine
WORKDIR /usr/share/nginx/html
COPY . /usr/share/nginx/html

2. Build image from Dockerfile
$docker image build -t thai:0.1 .

3. Create container from new image
$docker container -d thai:0.1

Working with container and volume

Using -v (volume) => format <host path>:<container path>
$docker container run -d -p 8081:80 -v $(pwd):/usr/share/nginx/html  nginx:1.15.5-alpine

For PWD (Play with docker)
1. Change own of folder and files to nginx
$chown -Rf nginx:nginx *

2. Create new container with volume
$docker container run -d -p 8081:80 -v $(pwd):/usr/share/nginx/html  nginx:1.15.5-alpine

Remove container when exited/stoped with --rm flag

$ docker container run -d --rm hello-world

Restart container

$docker run -dit  --restart=always  thai:0.1

Access to container and stop nginx process and see detail of container
$docker container exec -it 7a943f95c249 sh
#/kill 1
#exit

$ docker container ps
