Use Dockerfile to build images and push to a private warehouse

Environment: OS X 10.10.5

Maven 3.3.9

Docker version 1.12.2

Docker-machine version 0.8.2

The program example is the service Discovery program mentioned in http://www.cnblogs.com/modprobe/p/6001333.html

Related code: Https://github.com/li-hong/spring-cloud-demo

First, the preparation work, installs the Docker-toolbox

Method: Http://www.docker.com/products/docker-toolbox

After installation, use Docker-machine to create a virtual machine with a Docker runtime environment, or run Toolbox build directly

Command:

Docker-machine Create--driver VirtualBox default

Start a virtual machine

Docker-machine Start Default

Stop it

Docker-machine Stop Default

Log in to default using SSH

SSH Default

More commands to view using the following command

That's when the prep work is done.

Ii. Preparation of Dockerfile documents

From Java:8 #基础镜像VOLUME/tmp #将本地文件挂载到容器ADD Server-discovery-1.0-snapshot.jar app.jar #拷贝文件到容器RUN bash-C'Touch/app.jar' #运行命令EXPOSE8761 # Specifies the port that the container needs to map to the host machineentrypoint ["Java","-djava.security.egd=file:/dev/./urandom","-jar","/app.jar"] #容器启动后执行的命令

Third, build the image

Using Docker-manven-plugin to build MAVEN images, you can see how docker-maven-plugin is used in GitHub

Here's an overview:

Add a plugin to the POM

 <plugin>                <groupId>Com.spotify</groupId>                <Artifactid>Docker-maven-plugin</Artifactid>                <version>${docker.plugin.version}</version>                <executions>                    <Execution>                        <Phase>Package</Phase>                        <Goals>                            <goal>Build</goal>                        </Goals>                    </Execution>                </executions>                <Configuration>                    <ImageName>Lhdocker.com/${project.artifactid}</ImageName>                    <Baseimage>Java</Baseimage>                    <dockerdirectory>${project.basedir}/src/main/docker</dockerdirectory>                    <Dockerhost>https://192.168.99.100:2376</Dockerhost>                    <Dockercertpath>/users/lihong/.docker/machine/machines/default</Dockercertpath>                    <Resources>                        <Resource>                            <TargetPath>/</TargetPath>                            <Directory>${project.build.directory}</Directory>                            <include>${project.build.finalname}.jar</include>                        </Resource>                    </Resources>                </Configuration>            </plugin>

Notice what time

1, Dockerhost in the configuration to use the Docker-machine EVN command output docker_host

2, imagename in the lhdocker.com for their own private warehouse building, construction method see: Docker Registry-v2 build a private warehouse

3, if you want to upload to the private warehouse, and enable the user name password login, then you need to connect to the default in the login

SSHlogin lhdocker.com

After the configuration is complete, you can run the following command to build the image

MVN Clean Package Docker:build

If you succeed, you will see the following output

Build the image and upload it to the private warehouse

MVN Clean Package Docker:build  -dpushimage

After the success you will see the following additional output

Using Docker-images to view mirrors

Perform pull Tests

Now we're done using Docker-maven-plugin to build the Docker image and upload it to the private repository.

Iv. the pits encountered

1, not good environment preparation, direct operation

MVN Clean Package Docker:build

Encountered the following error output

[ERROR] Failed to execute goal com.spotify:docker-maven-plugin:0.4.  A 127.0. 0.1:4243 [/127.0.  0.11]

Solution, install the Docker-toolbox, and in the Pom species configuration Dockerhost

< Dockerhost >https://192.168.99.100:2376</dockerhost><  Dockercertpath>/users/lihong/.docker/machine/machines/default</  Dockercertpath>

2, run MVN Clean package Docker:build-dpushimage and encountered the following error

[ERROR] Failed to execute goal com.spotify:docker-maven-plugin:0.4.12:build (default) on Project Server-discovery:exception Caught:an HTTPS URI for Docker_host must is provided to use DOCKER client certificates, [Help 1]

Cause: Because the registry private warehouse is configured with its own certificate, Docker is not recognized, so in the default virtual machine type also need to import the certificate, the method is as follows

Where Lhdocker.com is doing the hosts map

SCP [Email protected]:/etc/docker/certs.d/lhdocker.com/lhdocker.com.crt/etc/docker/certs.d/lhdocker.com/
