As you’ve probably realised from previous posts, I’m very much into the idea of deploying my server applications via Docker, so let’s take the VertxTest application and create a Docker image with it.<\/p>\n

Thankfully we do not need to start our Dockerfile by creating a base OS then adding Java etc. The people writing Vert.x have kindly implemented a base image for us.<\/p>\n

See Deploying a Java verticle in a docker container<\/a>.<\/p>\n

If we take the example Dockerfile from their website and make the changes for our application (just replace VERTICAL_NAME and VERTICLE_FILE with our main verticle and the JAR) we get the following file<\/p>\n

\r\nFROM vertx\/vertx3\r\n\r\nENV VERTICLE_NAME com.putridparrot.MainVerticle\r\nENV VERTICLE_FILE VertxTest-1.0-SNAPSHOT-fat.jar\r\n\r\nENV VERTICLE_HOME .\r\n\r\nEXPOSE 8080\r\n\r\nCOPY $VERTICLE_FILE $VERTICLE_HOME\/\r\n\r\nWORKDIR $VERTICLE_HOME\r\nENTRYPOINT ["sh", "-c"]\r\nCMD ["exec vertx run $VERTICLE_NAME -cp $VERTICLE_HOME\/*"]\r\n<\/pre>\n
Place this Dockerfile into a folder along with the compiled JAR and then execute<\/p>\n
\r\ndocker build -t vertx_test  .\r\n<\/pre>\n
This creates an image name vertx_test which we can now execute. If you want to watch the output from our System.out.println<\/em> execute<\/p>\n
\r\ndocker run -it -p 8080:8080 vertx_test\r\n<\/pre>\n
Once you see the HTTP server started on port 8080<\/em> outputs, the Vert.x application will be ready for you to access via your preferred web browser etc. <\/p>\n","protected":false},"excerpt":{"rendered":"
