I had Jdk9 installed but project was using 1.8 I changed it to export JAVA_HOME=“$(/usr/libexec/java_home -v 1.8)” and worked.

[raghuchowdareddy]

Hi, Even I had faced above issue along with http 500 server exception Make sure below steps are working and in place

1. docker ps
2. docker-machine ls (at least default machine should be running) Some time docker-machine may not start properly. So I end up doing re-install the docker and start the docker-machine again $docker-machine env default export DOCKER_TLS_VERIFY=“1” export DOCKER_HOST=“tcp://192.168.99.100:2376” export DOCKER_CERT_PATH=“/Users/user-name/.docker/machine/machines/default” export DOCKER_MACHINE_NAME=“default”
3. Important: make sure you have the dockerfile naming convension as

“Dockerfile”

NOT

“DockerFile”

Because, i have seen some sites suggested to name like DockerFile, but it did not work for me 3. In pom.xml check the configuration as below <configuration> <dockerCertPath>/Users/username/.docker/machine/machines/default</dockerCertPath> <imageName>enterimangename</imageName> <dockerDirectory>${project.basedir}/src/main/docker</dockerDirectory> <dockerHost>https://192.168.99.100:2376</dockerHost> <serverId>docker-hub</serverId> <registryUrl>https://index.docker.io/v1/</registryUrl> <resources> <resource> <targetPath>/</targetPath> <directory>${project.build.directory}</directory> <include>${project.build.finalName}.jar</include> </resource> </resources> </configuration> 4. But last but not least in maven settings.xml <server> <id>docker-hub</id> <username>username</username> <password>pwd</password> <configuration> <email>[e-mail]</email> </configuration> </server> 5. Finally do “mvn clean install”
