Two methods of Web project Docker

The two methods described in the title are actually two ways to create a Docker image

First: After starting the mirror, go into the container, move the required software or items into the container, install or deploy, and then exit.

The second kind: Write Dockerfile, overlay the required mirrors layer by layer, for example, we want to deploy the project, we can first download an Ubuntu base image, then overlay the JDK, then Tomcat, then the project

I have tried both of these methods, the difference being that the second comparison embodies the image overlay feature of Docker, the first to eventually only one layer of mirroring.

First of all, my previous article has mentioned Dockerfile's writing, this way directly to give a simple dockerfile instance and run the command. Of course, before you write the underlying image, we choose Ubuntu: Run command

Docker search Ubuntu

Note: You can also run the Dockerfile file directly, and the specified base image must exist in the warehouse

The following results are obtained:

Choose the highest-rated first one, or you can choose Other, run:

Docker pull Ubuntu

After waiting for the download to complete, start writing dockerfile:

# version:1.0.02015-10-16 09:04"[email protected]"# Unzip the JDK installation package to /home/jdk1.8. 0_ 51ADD jdk-8u51-linux-x64.tar.gz/home/# Installs the Chinese language Pack #run locale-gen zh_cn. UTF-8/home/jdk1.80_51env CLASSPATH.: $JAVA _home/lib/dt.jar: $JAVA _home/lib/tools.jarenv PATH $PATH: $JAVA _home/bin# Set the locale variable env LANG ZH_CN. UTF-8ENV LANGUAGE Zh_cn:zh

As shown, put it well:

　　

Then run the command:

Docker BUILD-T Custom name path

The image will begin to be built so that a mirror with the base image and JDK is ready.

Then tomcat and Web projects are installed as above.

The first deployment method will then need to mount the directory locally when the mirror is launched:

Docker Run-i-t-v/root/software/:/mnt/software/53a0016cd0ba/bin/bash

Go inside the system:

Docker Exec-t-I 53a0016cd0ba/bin/bash

can see:

Now you can start to install the software and set the environment variables, because the system is also a common Linux operating environment, so here does not have to write specific installation and environment variable configuration

Finally, after deploying the Web project to the Tomcat directory, write a startup script that is ready to be called when the container starts, and take a look at my image instance:

The first one is the Web project I made, it should be pretty clear. It's been a long time. Some of the details have also been forgotten, please forgive me ...

In addition to the startup script mentioned above, you need to set the port mapping, that is, the-p parameter (you can also set the local network mode, do not expand) so that you can access the ...
