[Docker] Build Your Own Custom Docker Image

In this lesson we will cover how to build your own custom Docker image from scratch. We'll walk through the process of starting a Debian container, installing packages and working through configuration issues, as well as a strategy for building a Dockerfile.

 

// Installl debian then swich to bash interactive mode
docker run -it debian bash

// download tegine 
curl http://tengine.taobao.org/download/tengine-2.2.0.tar.gz > /opt/tengine-2.2.0.tar.gz

// If curl not found
apt-get update
apt-get install -y curl

// cd to the download folder and unzip the file
cd /opt
tar xzf tengine-2.2.0.tar.gz

// then you are able to see tegine-2.2.0 folder
cd tengine-2.2.0

// Check the document how to install tegine
apt-get install -y gcc
apt-get install -y libpcre3
apt-get install -y libssl-dev
./configure
pat-get install -y make
make
make install

// After tegine was install, cd to the sbin folder and run nginx
cd /usr/local/nginx/sbin
/usr/local/nginx/sbin/nginx
ps aux  //  check whether nginx started or not

 

Then we exit from the cmd:

exit

mkdir tengine
cd tengine/
vim Dockerfile

 

Building the docker file:

FROM debian
RUN apt-get update && apt-get install -y \
         curl \
         gcc \
         libpcre3-dev \
         libssl-dev \
         make

RUN curl http://tengine.taobao.org/download/tengine-2.2.0.tar.gz > /opt/tengine-2.2.0.tar.gz

WORKDIR /opt

RUN tar xzf tengine-2.2.0.tar.gz

WORKDIR /opt/tengine-2.2.0

RUN ./configure

RUN make

RUN make install

// Then we need to start nginx: https://github.com/nginxinc/docker-nginx/blob/4d1f7f8ec281117d1d79bed4c6bc28b86039ca84/stable/stretch/Dockerfile
// Can find cmd on Docker nginx hub

RUN ln -sf /dev/stdout /usr/local/nginx/logs/access.log \
    && ln -sf /dev/stderr /usr/local/nginx/logs/error.log

EXPOSE 80 443

CMD ["/usr/local/nginx/sbin/nginx", "-g", "daemon off;"]

 

Now we can build our image:

docker build -t zwan/tengine:2.2.0 .

Check images:

dcoker images

Run image:

docker run -p 8000:80 zwan/tengine:2.2.0

Then check localhost:8000.
