fabric8 8:docker-maven-plugin在Jenkins中的Centos7上运行时无法加载ffi提供程序

Question

在将fabric8添加到hello world pom之后，当在CentOS7上的Jenkins中运行maven“干净安装”时，

            <plugin>
                <groupId>io.fabric8</groupId>
                <artifactId>docker-maven-plugin</artifactId>
                <version>0.31.0</version>
                <configuration>
                    <filter>${*}</filter>
                    <images>
                        <image>
                            <name>docker.io/myname/${project.artifactId}:${project.version}</name>
                        </image>
                    </images>
                </configuration>
                <executions>
                    <execution>
                        <phase>package</phase>
                        <goals>
                            <goal>build</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin> 

我得到以下错误

[ERROR] Failed to execute goal io.fabric8:docker-maven-plugin:0.31.0:build (default) on project reference-service: Execution default of goal io.fabric8:docker-maven-plugin:0.31.0:build failed: An API incompatibility was encountered while executing io.fabric8:docker-maven-plugin:0.31.0:build: java.lang.UnsatisfiedLinkError: could not load FFI provider jnr.ffi.provider.jffi.Provider
[ERROR] -----------------------------------------------------
[ERROR] realm =    plugin>io.fabric8:docker-maven-plugin:0.31.0

..。

[ERROR] Number of foreign imports: 1
[ERROR] import: Entry[import  from realm ClassRealm[maven.api, parent: null]]
[ERROR] 
[ERROR] -----------------------------------------------------: could not get native definition for type: POINTER: java.lang.UnsatisfiedLinkError: /tmp/jffi5159674609596634370.so: /tmp/jffi5159674609596634370.so: failed to map segment from shared object: Operation not permitted

我找不到任何用于CentOS7的.so文件的安装说明或其他说明。

GitHub site没有提供太多的指导；

Docker正在监听2375和docker.sock。我正在构建的用户在dockerroot中。

fuse也有同样的问题

[ERROR] Failed to execute goal io.fabric8:docker-maven-plugin:0.23.0.fuse-730010-redhat-00001:build (default) on project reference-service: Execution default of goal io.fabric8:docker-maven-plugin:0.23.0.fuse-730010-redhat-00001:build failed: An API incompatibility was encountered while executing io.fabric8:docker-maven-plugin:0.23.0.fuse-730010-redhat-00001:build: java.lang.UnsatisfiedLinkError: could not load FFI provider jnr.ffi.provider.jffi.Provider
[ERROR] realm =    plugin>io.fabric8:docker-maven-plugin:0.23.0.fuse-730010-redhat-00001

Answer 1

在这种情况下，FFI错误意味着插件无法与docker守护进程通信。在全局jenkins配置中将DOCKER_HOST设置为tcp://127.0.0.1:2375解决了我的问题。
