Create docker file :
To deploy static website we will have to create one docker file to run website. in docker file we will add some text to perform tasks. copy the content below and paste in your docker file.
- Create directory called docker [you can create any]
mkdir /docker
- Create docker file in to docker directory and add below context.
vim dockerfile
FROM nginx:alpine
COPY . /usr/share/nginx/html
save file.
This Dockerfile will fetch the given Nginx Alpine docker image and copy data in present directory to the container.
copy all context from working directory to /usr/share/nginx/html.
touch index.html
<h1>Hellow this is my website</h1>
and save the file.
Now we will build the docker image. from the build command it will execute each instruction which we have added in docker file.
docker build -t mywebserver:v1 .
Sending build context to Docker daemon 3.072 kB
Step 1/2 : FROM nginx:alpine
alpine: Pulling from library/nginx

Status: Downloaded newer image for nginx:alpine
---> bc7fdec94612
Step 2/2 : COPY . /usr/share/nginx/html
---> 86c5b4596840
Removing intermediate container 8a769ed68528
Successfully built 86c5b4596840
Now you can see that build is success and downloaded nginx. we will check image using below command.
docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
mywebserver v1 86c5b4596840 About a minute ago 18 MB
Now we will run the image and launch the container from the image. i will bind it port to 9090 as i have already use 80.
docker run -d -p 9090:80 mywebserver:v1
31e18bf6c0337b69ded3328ad7affa45bf68f31253152e12ce099a1a13151975
i have define name of container [mywebserver and tag v1]
- Now you can see that our container is running.
docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
31e18bf6c033 mywebserver:v1 "nginx -g 'daemon ..." 37 seconds ago Up 35 seconds 0.0.0.0:9090->80/tcp amazing_clarke
Now you can check from web browser using host IP.
