Foreword
docker build mirroring, deployment springboot project is not new, because docker's continuous integration, version control, portability, and security isolation, etc., such that it is widely used.
Today, I will share with you a simple deployment process in Eureka.
Project Package
The simple premise of this article Eureka project uses Maven labeled jar package ( eureka-server-1.0.0.jar); Because Docker mounted Ali cloud, it will lay the jar on a cloud server (new folder /usr/local/dev/docker/testProject/),
specific packaging process there are many online sharing, not this go into detail.
Dockerfile
What is Dockerfile
Dockerfile Docker image is used to construct the build file, the script is a series of commands and configuration parameters.
Construction of three-step mirror
- Write Dockerfile file
- Dockerfile written documents and eureka-server-1.0.0.jar on the same level directory
- Content Dockerfile profile
FROM java:8
VOLUME /tmp
ADD eureka-server-1.0.0.jar /eureka-server.jar
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/eureka-server.jar"]
- java: 8 is to use jdk version
- VOLUME configuration data volume
- ADD copy files to and extract the mirror,
eureka-server-1.0.0.jarwe lay the jar package,eureka-server.jarmirroring a custom container name- Command to start the execution of the container when ENTRYPOINT
- Construction of execution Docker image
注意后面有个 .
docker build -t eureka-server .
- -t specify a new name eureka-server mirroring
- Indicates Dockfile in the current path
After creating the image, already present in this case Docker eureka-server mirroring.
- ** running just built into the mirror *
docker run -d -p 1001:1001 --name eureka-server eureka-server
- -d background
- -P jar coated with port 1001, the host 1001 port mapping, the container port 1001
- --name: the name of the specified container
By docker psCheck that the container is already running
- Browser access
HTTP: ip + 1001 Eureka successful start
