   Hi Ondrej!! nice article.

   I execute all the steps without problems until 5.2 ( Running the main application in Docker).

   This is my problem:

   The guide says: “docker run -p 8080:8080 -v ‘PATH_TO_THE_GITHUB_REPO/cargo-tracker/
   target/autodeploy’:/opt/payara41/deployments reactivems/payara-server
   bin/asadmin start-domain -v”

   I replaced it command with:

   docker run -p 8080:8080 -v ‘/Users/josediaz/Projects/MicroProfile/ReactiveWay-cargotracker/target/autodeploy’:/opt/payara41/deployments reactivems/payara-server bin/asadmin start-domain -v

   The commando ‘docker ps -a’ shows:

   3f623b6c44a3 reactivems/payara-server “bin/asadmin start-d…” 29 minutes ago Up 29 minutes 4848/tcp, 5900/tcp, 8009/tcp, 8181/tcp, 0.0.0.0:8080->8080/tcp reverent_edison

   But the url is not running:

   http://localhost:8080/cargo-tracker/

   returns error 404.

   Can you help me with some tip?

   Jose

   Hi Jose, I’m glad you like the workshop lecture and that you got so far without any problems. I realized the instructions for running in docker are obsolete and I forgot to fix them.

   Instead of using the custom reactivems/payara-server image which isn’t needed anymore, use the standard Payara 5 image with the following:

   docker run -p 8080:8080 -v ‘/Users/josediaz/Projects/MicroProfile/ReactiveWay-cargotracker/cargo-tracker/target/autodeploy’:/opt/payara/deployments payara/server-full

   And then to execute Payara Micro instances, run the following (you need to supply the internal IP address of the Payara Server container):

   docker run -v ‘PATH_TO_THE_GITHUB_REPO/pathfinder/target’:/opt/payara/deployments payara/micro java -jar /opt/payara/payara-micro.jar –deploy /opt/payara/deployments/pathfinder.war –clustermode domain:IP_OF_PAYARA_SERVER_CONTAINER:4900

   The first command run successfully.
   But the second give it error:

   ocker run -v ‘/Users/josediaz/Projects/MicroProfile/ReactiveWay-cargotracker-ext/pathfinder/target’:/opt/payara/deployments payara/micro java -jar /opt/payara/payara-micro.jar –deploy /opt/payara/deployments/pathfinder.war –clustermode domain:172.17.0.2:4900

   Ok I found the fix.

   docker run -v ‘/Users/josediaz/Projects/MicroProfile/ReactiveWay-cargotracker-ext/pathfinder/target’:/opt/payara/deployments payara/micro –deploy /opt/payara/deployments/pathfinder.war –clustermode domain:172.17.0.2:4900

   java -jar /opt/payara/payara-micro.jar is not necessary anymore.

   Thanks Ondrej
