What is the difference between docker and jenkins

The difference between docker and jenkins: 1. Docker is developed based on go language, while jenkins is developed using java; 2. Docker adopts the "Apache 2.0" open source protocol, and jenkins adopts the MIT open source protocol; 3. Docker is a virtualization A container is a virtual machine, and Jenkins is used to continuously and automatically build and test software projects.

The operating environment of this tutorial: linux7.3 system, docker version 19.03, Dell G3 computer.

What is the difference between docker and jenkins

Docker is a virtualization container, which is a virtual machine. It is based on Go language and adopts the Apache 2.0 open source protocol. It is divided into EE (Enterprise Edition) and CE (Community Edition), the Enterprise Edition is charged, and the Community Edition is free

jenkins is developed in Java and adopts the MIT open source protocol. It is mainly used to continuously and automatically build/test software projects and monitor some To execute scheduled tasks, you can use docker to complete the automated construction tasks of Java projects

The difference between the two can be explained with a picture

It can be seen that jenkins acts as an automatic build, and Docker is equivalent to a virtual machine, or a container.

Expand knowledge

Jenkins is an open source software project, a continuous integration tool developed based on Java, used to monitor continuous repetitive work. In providing an open and easy-to-use software platform, software projects can be continuously integrated

Jenkins functions include:

1. Continuous software version release/testing projects.

2. Monitor the work performed by external calls.

Startup:

First ensure that jdk has been installed in the system, preferably jdk1.5 or above.

The first startup method is to switch to the directory where jenkins.war is stored and enter the following command:

$ java -jar jenkins.war

If you need to modify the port, you can use the following command:

$ java -jar jenkins.jar--httpPort=8081

Then in Enter localhost:8081 in the browser (Firefox is recommended). localhost can be the local IP or the computer name. You can open jenkins.

The second method is to open it with tomcat

Extract tomcat to a directory, such as /usr/local, enter the /bin directory under tomcat, and start tomcat

The jenkins.war file is placed in the webapps directory under tomcat. When starting tomcat, the jenkins directory will be automatically created in the webapps directory. You need to enter localhost:8080/jenkins in the address bar.
