[FIXED] jib-maven-plugin I/O error for image [registry-1.docker.io/library/adoptopenjdk]

Issue

I have developed a Dockerized Spring Boot Application using as base image AdoptOpenJDK and using jib-maven-plugin.

My plugin configuration is:

                <plugin>
                    <groupId>com.google.cloud.tools</groupId>
                    <artifactId>jib-maven-plugin</artifactId>
                    <version>${jib-maven-plugin.version}</version>
                    <configuration>
                        <from>
                            <image>adoptopenjdk:11-jre-hotspot</image>
                        </from>
                        <to>
                            <image>public/my-app</image>
                            <tags>
                                <tag>latest</tag>
                                <tag>${project.version}</tag>
                            </tags>
                        </to>
                        <container>
                            <entrypoint>
                                <shell>bash</shell>
                                <option>-c</option>
                                <arg>/entrypoint.sh</arg>
                            </entrypoint>
                            <ports>
                                <port>8080</port>
                            </ports>
                            <environment>
                                <SPRING_OUTPUT_ANSI_ENABLED>ALWAYS</SPRING_OUTPUT_ANSI_ENABLED>
                                <JHIPSTER_SLEEP>0</JHIPSTER_SLEEP>
                            </environment>
                            <creationTime>USE_CURRENT_TIMESTAMP</creationTime>
                        </container>
                        <extraDirectories>
                            <paths>src/main/jib</paths>
                            <permissions>
                                <permission>
                                    <file>/entrypoint.sh</file>
                                    <mode>755</mode>
                                </permission>
                            </permissions>
                        </extraDirectories>
                    </configuration>
                </plugin>

Everything is OK, and the app is builded correctly when launch ./mvnw package -Pprod -DskipTests jib:build -T16.0C. Now I'm integrating my app in a CI/CD Jenkins Pipeline and I'm creating a command like the first but passing Auth data using variables:

 ./mvnw -ntp -T2.0C jib:build -Djib.from.auth.username=myUserName -Djib.from.auth.password=mygitlabtoken01 -Dimage=registry.gitlab.com/myapp -X 

When I run it i get:

[INFO] Using credentials from Docker config (/Users/myUser/.docker/config.json) for registry.gitlab.com/neoris-emea-internal/ianthe/ianthe-app/ianthe
[DEBUG] attempting bearer auth for registry.gitlab.com/app...

[ERROR] I/O error for image [registry-1.docker.io/library/adoptopenjdk]:
[ERROR]     javax.net.ssl.SSLHandshakeException
[ERROR]     Remote host terminated the handshake

I do not understand anything:

• Why jib plugin is using my .docker/config.json if I have indicated the auth info with -Djib.from.auth.username=myUserName?
• Why am I getting SSLHandshakeException? Although the build is using my credentials, these are correct.

Solution

If you look at the log messages carefully, Jib did use your credentials you specified via from.auth.username|password for adoptopenjdk (which is hosted on Docker Hub).

Using credentials from <from><auth> for adoptopenjdk:11-jre-hotspot

Note the following line says the Docker config is used for registry.gitlab.com (the target registry).

Using credentials from Docker config (/Users/myUser/.docker/config.json) for registry.gitlab.com/neoris-emea-internal/ianthe/ianthe-app/ianthe

About the SSLHandshakeException, it has nothing to do with any Docker credentials. The error is from a much lower network layer (TLS protocol), so the failure is fundamentally unrelated to Jib or any application running in the JVM on Jenkins. It is basically telling you that any Java app on the JVM just cannot make a secure TLS connection to some hosts. There is no simple answer or solution to a TLS handshake failure, so get some help from a network and TLS expert if possible. Also check out other SO questions like this one.
