Configuring TCP remote connections
Why To configure this, because the use of docker-maven-plugin plug-default connection to localhost: docker on 2375. However: 1 to set before our Docker is not local, the implementation of the order to pack environment variables [ DOCKER_HOST = tcp: // <host> : 2375 ]; 2 Docker default tcp remote connection is closed, so we want to open.
Method One : Before we configure Ali cloud images when a new file daemon.json, now have to use this. It is to configure [ "hosts": [ "tcp: //0.0.0.0: 2375", "unix: ///var/run/docker.sock"] ]
Vim / etc / Docker / daemon.json # add the following, application specific address of its slightly { " Registry-Mirrors " : [ " HTTPS: //****.mirror.aliyuncs.com " ], " the hosts " : [ " tcp: //0.0.0.0: 2375 " , " UNIX: ///var/run/docker.sock " ] } # to restart the service systemctl daemon - reload systemctl restart Docker
Then open the firewall port 2375
[root@localhost admin]# firewall-cmd --zone=public --add-port=2375/tcp --permanent success [root@localhost admin]# systemctl restart firewalld
Test on whether access can be accessed in a browser, you can also curl in a virtual machine
If a virtual machine
[root@localhost admin]# curl localhost:2375 {"message":"page not found"}
Method Two :
[root@localhost admin]# vim /lib/systemd/system/docker.service [Unit] Description=Docker Application Container Engine Documentation=http://docs.docker.com After=network.target rhel-push-plugin.socket registries.service Wants=docker-storage-setup.service Requires=docker-cleanup.timer [Service] Type=notify NotifyAccess=all EnvironmentFile=-/run/containers/registries.conf EnvironmentFile=-/etc/sysconfig/docker EnvironmentFile=-/etc/sysconfig/docker-storage EnvironmentFile=-/etc/sysconfig/docker-network Environment=GOTRACEBACK=crash Environment=DOCKER_HTTP_HOST_COMPAT=1 Environment=PATH=/usr/libexec/docker:/usr/bin:/usr/sbin ExecStart=/usr/bin/dockerd-current \ --add-runtime docker-runc=/usr/libexec/docker/docker-runc-current \ --default-runtime=docker-runc \ --exec-opt native.cgroupdriver=systemd \ --userland-proxy-path=/usr/libexec/docker/docker-proxy-current \ --init-path=/usr/libexec/docker/docker-init-current \ --seccomp-profile=/etc/docker/seccomp.json \ $OPTIONS \ $DOCKER_STORAGE_OPTIONS \ $DOCKER_NETWORK_OPTIONS \ $ADD_REGISTRY \ $BLOCK_REGISTRY \ $INSECURE_REGISTRY \ $REGISTRIES ExecReload=/bin/kill -s HUP $MAINPID LimitNOFILE=1048576 LimitNPROC=1048576 LimitCORE=infinity TimeoutStartSec=0 Restart=on-abnormal KillMode=process [Install] WantedBy=multi-user.target
The last new red shown below wherein ExecStart
ExecStart=/usr/bin/dockerd-current \ --add-runtime docker-runc=/usr/libexec/docker/docker-runc-current \ --default-runtime=docker-runc \ --exec-opt native.cgroupdriver=systemd \ --userland-proxy-path=/usr/libexec/docker/docker-proxy-current \ --init-path=/usr/libexec/docker/docker-init-current \ --seccomp-profile=/etc/docker/seccomp.json \ $OPTIONS \ $DOCKER_STORAGE_OPTIONS \ $DOCKER_NETWORK_OPTIONS \ $ADD_REGISTRY \ $BLOCK_REGISTRY \ $INSECURE_REGISTRY \ $REGISTRIES \ -H unix:///var/run/docker.sock \ -H tcp://0.0.0.0:2375
Then restart the service, you can still meet the needs of
# Restart the service systemctl daemon - reload systemctl restart Docker
Configure private warehouse
Go look at the configuration file
[root@localhost admin]# vim /etc/docker/daemon.json # 在最后加上仓库配置 { "registry-mirrors": ["https://****.mirror.aliyuncs.com","http://hub-mirror.c.163.com"], "hosts": ["tcp://0.0.0.0:2375","unix:///var/run/docker.sock"], "insecure-registries":["192.168.192.128:443"] }
Then download the image registry, start, I was the registry 5000 container port mapping to the host port 443, and you are free
[root@localhost admin]# docker pull registry Using default tag: latest Trying to pull repository docker.io/library/registry ... latest: Pulling from docker.io/library/registry c87736221ed0: Pull complete 1cc8e0bb44df: Pull complete 54d33bcb37f5: Pull complete e8afc091c171: Pull complete b4541f6d3db6: Pull complete Digest: sha256:8004747f1e8cd820a148fb7499d71a76d45ff66bac6a29129bfdbfdc0154d146 Status: Downloaded newer image for docker.io/registry:latest [root@localhost admin]# docker run -d -p 443:5000 registry b56713ddca3f4b5903cc456002624a6cd6a6b3b79b8a542b873c461ed31b1b3b
Remember to open firewall ports, refer to the above
[Put on all data and files are deleted after docker mirror removed, so take a local directory on the host to mount directories inside the vessel registry, after deleting registry files and container still ensure data is not lost]
Nothing but first create a directory on the host, and then start the registry when using the -v parameter to be mapped. Similar to the following:
Into the interior of the vessel registry, see the directory in which it
[root@localhost admin]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES b56713ddca3f registry "/entrypoint.sh /e..." 36 minutes ago Up 21 minutes 0.0.0.0:443->5000/tcp confident_ [root@localhost admin]# docker exec -it b56713ddca3f sh / # find / -name registry /bin/registry /etc/docker/registry find: /proc/scsi: Permission denied find: /sys/firmware: Permission denied /var/lib/registry /var/lib/registry/docker/registry
It can be seen mount var / lib / registry directory, so:
Stop # container [root @ localhost ADMIN] # Docker STOP b56713ddca3f b56713ddca3f # delete container [root @ localhost ADMIN] # Docker RM b56713ddca3f b56713ddca3f # Create the host directory mkdir / usr / docker_registry_data # launch container Docker RUN -d -p 443 : 5000 -v / usr / docker_registry_data: / var / lib / registry registry

Docker required to push the image name to the host name and port warehouse as a prefix. For example, my-image to be pushed registry.example.com, the mirror to be marked as registry.example.com/my-image -> < imageName > 192.168.192.128:443/hello </ imageName > <-! Base image -> < baseImage > Java </ baseImage > < the entryPoint > [ "Java", "-jar", "/${project.build.finalName}.jar"] </ the entryPoint > <-!

Then build, configure docker address, and then execute build command
SET DOCKER_HOST=tcp://192.168.192.128:2375 mvn clean package -Dmaven.test.skip=true docker:build -DpushImageTag
Back to the server to view mirror

The first push above, the output will be a lot of things, but after a push would not, as follows:
