Pushing the image to Docker Hub takes a long time

Environment:

• Jib version: 1.5.0
• Build tool: Gradle 5.6.2
• OS: MacOSX 10.14.6

Description of the issue:

Push the image to Docker Hub initially takes extremely long (almost 5 mins). Subsequent push operations are much faster (seconds).

Expected behavior:

Pushing an image to Docker Hub should match the execution time when using Docker Engine.

Steps to reproduce:

1. Clone https://github.com/bmuschko/todo-web-service
2. Execute ./gradlew jib

Log output:

$ ./gradlew jib

> Task :jib

@TadCordle Thanks. I tried it out and its close to the numbers I see with version 1.4.0.

@kalapraveen-mi are you using <allowInsecureRegistries> by any chance? If that is the case, I worry that 1.4.0 might be the last version that may seem to “work” (in a very inefficient way) in your case. I could be wrong about your case though.

@chanseokoh No, I am not using any such tag and logged into Docker container on Mac. We are using Jib plugin and is run as part of “deploy” phase in the following way:

<plugin>
                <groupId>com.google.cloud.tools</groupId>
                <artifactId>jib-maven-plugin</artifactId>
                <version>1.4.0</version>
                <configuration>
                    <from>
                        <image>BASE_IMAGE_NAME</image>
                    </from>
                    <to>
                        <image>TARGET_IMAGE_NAME:${project.version}</image>
                    </to>
                    <container>
                        <ports>
                            <port>8085</port>
                            <port>9085</port>
                        </ports>
                        <environment>
                            <MAIN_CLASS>APP_CLASS</MAIN_CLASS>
                        </environment>
                        <entrypoint>/usr/local/bin/entrypoint.sh</entrypoint>
                    </container>
                </configuration>
                <executions>
                    <execution>
                        <phase>deploy</phase>
                        <goals>
                            <goal>build</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

Now, when I run the build of the project version contains SNAPSHOT it gets pushed effortlessly as it always does. However, if the ${project.version} contains a release it struggles and ends up with a credentials error. The same code works if I explicitly specify the version 1.4.0.

We push to dockerhub by the way. Hope this info helps. Thank you very much!
