In three ways you can build/create a container images.Д«uild and keep your docker image ready for upload by following any one of the methods listed above. LetвЂ™s create a Docker image (for customized docker container) for uploading it into the private registry server. Login into your build Docker engine node, Ex. Create and upload a Docker Image to a Private Registry server Now the Docker Registry is ready for distributing Docker images. If your Docker Registry is on Ubuntu 16.04, ufw ufw allow ufw reload ufw enable If your Docker Registry is on CentOS 7 / Fedora 26/25, ~]# firewall-cmd -permanent ~]# firewall-cmd -reload You need to run the following command on Docker Registry server (), depends on your operating system. You would need to open following ports on firewall for Docker registry to be available outside network (to / ) Output: CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMESДЁ641fbc895f5 registry '/entrypoint.sh /e.' 44 seconds ago Up 41 seconds 0.0.0.0:5000->5000/tcp registry Firewall Now, you have a registry server container named вЂњ registryвЂќ running on вЂњ вЂњ. ~]# docker run -d -p 5000:5000 -restart=always -name registry -v /certs:/certs -e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/ca.crt -e REGISTRY_HTTP_TLS_KEY=/certs/ca.key registry Start Docker registry container with certificate information. Generated certificate вЂњ ca.crtвЂќ need to be placed on all of your build/deploy nodes for trusting this certificate. Organizational Unit Name (eg, section) :ITД¬ommon Name (eg, your name or your server's hostname) : Д®mail Address вЂњ вЂќ with the FQDN of your registry server. If you enter '.', the field will be left blank. There are quite a few fields but you can leave some blankДЇor some fields there will be a default value, What you are about to enter is what is called a Distinguished Name or a DN. You are about to be asked to enter information that will be incorporated Writing new private key to '/certs/ca.key' ~]# mkdir -p ~]# openssl req -newkey rsa:4096 -nodes -sha256 -keyout /certs/ca.key -x509 -days 365 -out /certs/ca.crt LetвЂ™s create a self-signed certificate using the following command. Here, I will use a self-signed certificate for securing Docker Registry. You can use TLS certificates signed by CA or self-signed on Registry server.

Plain Docker Registry ~]# docker run -dit -p 5000:5000 -name registry registry Secure Docker Private RegistryД«y default, Docker node uses a secure connection over TLS to upload or download images to or from the private registry. ~]# docker pull registryД¬hoose whether you want to go with plain or secured Docker registry. Login to registry node and pull the registry image from Docker Hub.

I recommend you to use only homogeneous environment which is easy for troubleshooting issues that arise. Here, IвЂ™m using mixed (OS) environment to demonstrate. Infrastructure Setup Docker Private Registry on CentOS 7 HostNameДЄcts as Docker engine node where the developers will build the Docker images either with dockerfile or docker compose, and then upload those images to above docker private registry server.ДЄcts as Docker engine node where we deploy containers downloaded (pull) from private registry server. Here, in this tech guide, we will discuss on how to setup Docker Private Registry on CentOS 7/ Ubuntu 16.04 / Fedora 26/ 25. To overcome this hurdle, you can set up a Docker registry for your project privately so that only you or your organization can store the Docker images on it and distribute among your co-worker. This is not what you or your organization expect when you worked for long hours to build an image and that goes public.

Docker even has a public registry, known as Docker Hub, free to store Docker images.Д«ut, the problem with Docker public registry is that the images you upload on it becomes public. Docker registry is a piece of application that lets you store and distribute the Docker images internally (within your organization).
