I, on the Registry
The official Docker hub is a good place for managing the public image, we can find the image we want on it, you can also push up our own image.
But sometimes we use scenario we need to have a private warehouse mirror for managing our own image. This purpose can be achieved by open source software Registry.
Registry There are two code on github: old code base and new code base. Old code that is written using python, there is a pull and push performance issues, then out to the 0.9.1 version are marked as deprecated, no longer continue to develop.
It is to be from the start of the new version 2.0 code base development, new code base is written using go, modifies image id generation algorithm, registry stored on mirrored structure, greatly improving the efficiency of pull and push mirroring.
The official registry of the image on Docker hub, we can directly use the registry to construct a mirror container, to build our own private warehouses.
Second, build Registry
First, search for and pull the mirror
Search Registry Docker # recommended that you search, you can look at the relevant mirror, maybe someday have a better image of the Docker pull Registry # label can not add, because the current is the latest v2
Run a registry container
RUN -d Docker \ # run in the background --name Registry-SRV \ # specified container name --restart = Always \ # set to automatically start -p 5000: 5000 \ # port mapping host, accessed by the host address -v / opt / ZWX-Registry: / var / lib / Registry \ # the mirror mounts to the local storage directory, easy to manage and persistence -v /opt/zwx-registry/srv-config.yml:/etc/docker/registry/config .yml \ # the mount configuration files to a local, easy to modify and save registry
srv-config.yml follows
Marked red delete parameter set to true, is to allow the warehouse to support delete function. Without this default parameter, which is the mirror image can not be deleted warehouse.
version: 0.1 log: fields: service: registry storage: delete: enabled: true cache: blobdescriptor: inmemory filesystem: rootdirectory: /var/lib/registry http: addr: :5000 headers: X-Content-Type-Options: [nosniff] health: storagedriver: enabled: true interval: 10s threshold: 3
Registration https protocol (otherwise push hard on safety certification)
Required by local repository download the image, all you need to configure
/etc/docker/daemon.json vim # default is no such file, add their own, there is the additional following. { " In the insecure-Registries " : [ " xx.xx.xx.xx: 5000 " ]} # specify the IP address or domain name
systemctl daemon -reload # daemon restart systemctl docker restart # restart docker Service
Mirror upload and download
the Push xx.xx.xx.xx Docker: 5000 / nginx # must indicate the address of the warehouse, otherwise it will error docker pull xx.xx.xx.xx: 5000 / nginx
View Mirror Information Warehouse
-XGET HTTP curl: //xx.xx.xx.xx: 5000 / v2 / _catalog # View warehouse mirror list (also open to view through the windows browser) curl -XGET HTTP: //xx.xx.xx.xx: 5000 / v2 / image_name / Tags / List # View application image tag specified
Third, build Registry web
First, search for and pull the mirror
docker search docker-registry-web Hyper pull Docker / Docker-Registry Web- # this image with more people
Run a registry web container
RUN -d Docker \ # run in the background --name-Registry Web \ # specified container name --restart = Always \ # set to automatically start -p 8000: 8080 \ # port mapping host, accessed by the host address -v / opt /zwx-registry/web-config.yml:/etc/config.yml \ # the mount configuration files to a local, easy to modify and save hyper / docker-registry-web
web-config.yml document reads as follows
Marked red readonly parameter set to false, in order to web page may delete button. The default is true, read-only, no delete button, can only view.
registry: # Docker registry url url: http://10.88.77.32:5000/v2 # Docker registry fqdn name: localhost:5000 # To allow image delete, should be false readonly: false auth: # Disable authentication enabled: false
After the deployment is complete, open the repository browser UI to see to address all application image
Select any application image gallery to see all the tag information of the mirror, behind each tag has a delete button (not the default configuration reference config.yml)
Fourth, fast deployment
Cluster mode can quickly deploy registry and registry web by docker stack.
New profile srv-config.yml, web-config.yml into the designated path, then the new docker-compose.yml file, execute command.
docker stack deploy -c docker-compose.yml RGT
Version: '3.7 ' # Docker Stack 3.0 or later is required services: Registry - SRV: # service name image: registry the ports: # mapping port --5000: 5000 Volumes: # configuration file path and mount the mirror, change the path consistent with the actual note - / opt / ZWX-Registry: / var / lib / Registry - /opt/zwx-registry/srv-config.yml:/etc/docker/ Registry / config.yml Deploy: # Set a single task, and the main constraint nodes running mode: replicated replicas: 1 placement: constraints: - node.role == manager Registry - Web: # service name Image: Hyper / Docker-registry- Web the ports: # mapping port --8000: 8080 Volumes: # mount configuration file, pay attention to modify the path consistent with the actual - /opt/zwx-registry/web-config.yml:/conf/ config.yml environment: - REGISTRY_URL=http://registry-srv:5000/v2 - REGISTRY_NAME=localhost:5000 Deploy: # Set a single task, and the main constraint nodes running mode: replicated replicas: 1 placement: constraints: - node.role == manager
