Deploying SpringBoot Struts 2 Integration Project in Docker

 Follow my previous post and create the sample spring struts integration project from here.

Create a Docker File: Dockerfile

FROM tomcat:latest

ADD target/SpringStrutsDemo-0.0.1-SNAPSHOT.war /usr/local/tomcat/webapps/

EXPOSE 8080

CMD ["catalina.sh","run"]

Build and tag the Docker File:spring-strutsdemo

C:\Users\Syed\Spring-workspace\SpringStrutsDemo>docker build -t spring-strutsdemo .

Sending build context to Docker daemon  58.75MB

Step 1/4 : FROM tomcat:latest

 ---> 5505f7218e4d

Step 2/4 : ADD target/SpringStrutsDemo-0.0.1-SNAPSHOT.war /usr/local/tomcat/webapps/

 ---> a30a842ce761

Step 3/4 : EXPOSE 8080

 ---> Running in 35d616d2803f

Removing intermediate container 35d616d2803f

 ---> 2c848691227a

Step 4/4 : CMD ["catalina.sh","run"]

 ---> Running in 270c9c8d4b5d

Removing intermediate container 270c9c8d4b5d

 ---> f7b915b47c1f

Successfully built f7b915b47c1f

Successfully tagged spring-strutsdemo:latest

Run the docker image from the tag 

docker run -p 8080:8080 spring-strutsdemo

This will start in 8080 port. In case if it is not started well there could be an issue with the java version used in the docker or the project is not properly generated and war is invalid.

Access it using 

http://localhost:8080/SpringStrutsDemo-0.0.1-SNAPSHOT/message.action

where SpringStrutsDemo-0.0.1-SNAPSHOT is the context. 

Happy Learning!!!!
