The use substantially Docker - Application of the packaged mirror image Spring Boot and Run

Step 1

Find a spring boot project can run here with a chapter-1-spring-boot-quickstart-1.0.jarspringboot project can run
(here I use the cloud service Ali lightweight application server)
to prepare a Dockerfilefile

FROM java:8-alpine
ADD chapter-1-spring-boot-quickstart-1.0.jar springboot.jar
EXPOSE 8090
ENTRYPOINT ["java","-jar","/springboot.jar"]

Description:

• FROM Specifies the source base image composed of a mirror, such as the project to rely jdk environment (8-alpine version of java representatives)
  can be found on the official websitehttps://hub.docker.com
• ADD copied to the local file system file of the target vessel ( chapter-1-spring-boot-quickstart-1.0.jarthe representative file, springboot.jarrepresentative of a target file to be generated)
• External port EXPOSE container map (of course, when the back of the container may be specified at runtime mirror)
• ENTRYPOINT container configuration command is executed after startup, the third parameter springboot.jarto the second parameter and the rear consistent ADD

Step 2

The two documents prepared by the above: chapter-1-spring-boot-quickstart-1.0.jar, Dockerfileuploaded to the linux server

Step 3

Input docker build -t springboot .to build the image
Note: springbootthe future generation of image name, .but also do not forget

[root@izwz91m0zmp2dlo94i0ptoz lee]# docker build -t springboot .
Sending build context to Docker daemon 14.33 MB

Step 4/4 : ENTRYPOINT java -jar /springboot.jar

Removing intermediate container 80f0e8c17027
Successfully built e33afac4394a

You can see the success of the last generation of the mirror can also docker imagesview to:

This post is simple, this is the basis for the use of a combination of springboot and docker, please correct me if wrong, we learn together

If there are not very familiar with the command of the Docker, please refer to another article I Bowen: the basic use of Docker
