I/O exception(java.io.IOException)caught when processing request to{}->unix://localhost:80:No such file or directory -when build image frm Dockerfile

问题

I want to create a image for maven project using Dockerfile in Jenkins. This is a spring boot project. I have run the Jenkins as a Docker container. I am using Windows 10.

My Dockerfile is:

FROM maven:3.5-jdk-8-alpine
WORKDIR /app
COPY pom.xml /app/
COPY Dockerfile /app/
RUN ["mvn", "package"]

FROM tomcat:9
EXPOSE 8087
COPY /app/target/*.war /usr/local/tomcat/webapps/
CMD ["catalina.sh", "run"]

And the plugin part of pom.xml is:

<plugins>
    <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
        <configuration>
            <mainClass>com.example.restcurd.RestcurdApplication</mainClass>
        </configuration>
    </plugin>

    <plugin>
        <groupId>com.spotify</groupId>
        <artifactId>dockerfile-maven-plugin</artifactId>
        <version>1.4.10</version>
        <executions>
            <execution>
                <id>build</id>
                <phase>package</phase>
                <goals>
                    <goal>build</goal>
                </goals>
            </execution>
        </executions>
        <configuration>
            <repository>pomkiticat/${project.name}</repository>
            <tag>${project.version}</tag>
            <skipDockerInfo>true</skipDockerInfo>
            <pullNewerImage>false</pullNewerImage>
        </configuration>
    </plugin>
</plugins>

In Jenkins Docker settings:
I/O exception(java.io.IOException)caught when processing request to{}->unix://localhost:80:No such file or directory -when build image frm Dockerfile

I have also selected the option Expose daemon on tcp://localhost:2375 without TLS in Docker Desktop.

But I am getting the error:

[INFO] ------------------------------------------------------------------------

[ERROR]

I found a solution for the problem. I got some solutions, i.e., to set the Docker Host Uri. I have already set it and attached the image above.

How can I solve the problem? Thanks in advance.

当一个进程尝试写入到Docker守护程序套接字,但缺乏权限时会发生这种情况。

请检查/var/run/docker.sock是否对尝试创建Docker镜像的用户可访问。特别是,默认情况下只有root用户和组具有写入docker.socket的权限,因此尝试执行chmod o+w /var/run/docker.sock以允许其他用户写入到Docker守护程序套接字,然后问题应该解决了。

英文:

It happens when a process tries to write to the docker daemon socket but it lacks of permissions.

Check that /var/run/docker.sock is accessible for the user that tries to create the docker image. In particular, by default only root and the group has rights to write to docker.socket, so try executing chmod o+w /var/run/docker.sock in order to allow others to write into the docker daemon socket and then the issue should be gone.

这在Fedora上对我有效:

 export DOCKER_HOST=unix:///var/run/docker.sock
 service docker restart
 mvn clean install -DskipTests
英文:

This worked for me on Fedora

 export DOCKER_HOST=unix:///var/run/docker.sock
 service docker restart
 mvn clean install -DskipTests

sudo setfacl --modify user:<用户名或ID>:rw /var/run/docker.sock

英文:

worked for me:

sudo setfacl --modify user:&lt;user name or ID&gt;:rw /var/run/docker.sock

I faced with this error too with ubuntu 22.4 and docker desktop.
In my case the problem was in "docker context". Maven can't use these contexts and use standard (unix:///var/run/docker.sock or unix://localhost:80). But docker desktop uses your home directory by default and there is not docker engine on standard socket.
You can see your contexts by command:

docker context ls
In my case the answer is:

NAME DESCRIPTION DOCKER ENDPOINT
default * Current DOCKER_HOST based configuration unix:///var/run/docker.sock
desktop-linux Docker Desktop unix:///home/sergey/.docker/desktop/docker.sock

To fix it all you need is set DOCKER_HOST to your "desktop-linux" endpoint, in my case:

export DOCKER_HOST=unix:///home/sergey/.docker/desktop/docker.sock
And "mvn dockerfile:build" starts working! You can put the DOCKER_HOST var in /etc/environment.

Maybe I answered on a bit other question but I believe this might help someone.
This helped me to find the solution.
