Explanation of the process of docker packaging node project

As a backend programmer, sometimes I have to tinker with frontend stuff. So, my boss asked me to package the front-end project into a docker package. Okay, let’s stop talking nonsense. To install the docker package, you must first have a dockerfile, so let's write docker first

Dockerfile

FROM daocloud.io/node:7
MAINTAINER abel.yang <[email protected]>
LABEL Description="This image is built for web"
RUN mkdir -p /opt/apps/epp
COPY . /opt/apps/epp
WORKDIR /opt/apps/epp/epp-web/server
ENV LANG C.UTF-8
ENV TZ=Asia/Shanghai
RUN ln -snf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && echo Asia/Shanghai > /etc/timezone
EXPOSE 3001
CMD [ "npm", "start" ]

Okay, the Dockerfile is written and executes the image creation command.

myeppweb is the name of the mirror I typed

docker build -t myeppweb .
// Note. Don't forget.

start up

At this time, execute docker images to view the successfully packaged image

Execute the startup command:

docker run -d -p 3001:3001 myeppweb

analyze

Okay, let me explain the command of dockerfile

Package the image based on the image of daocloud.io/node:7

FROM daocloud.io/node:7

This is the maintainer's information.

MAINTAINER abel.yang <[email protected]>
LABEL Description="This image is built for web"

Create a folder and move all the files in the current folder into the new folder. (The files in my current folder are the front-end executable code. You can run the code by simply typing npm run start)

RUN mkdir -p /opt/apps/epp
COPY . /opt/apps/epp

Set the current path, that is, all the following commands are executed in this path

WORKDIR /opt/apps/epp/epp-web/server

Set the mirror time and time zone

ENV LANG C.UTF-8
ENV TZ=Asia/Shanghai
RUN ln -snf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && echo Asia/Shanghai > /etc/timezone

Exposed Ports

EXPOSE 3001

Start the node

CMD [ "npm", "start" ]

Well, this article just records the packaging process.
