docker-machine - a tool that lets you install Docker Engine on virtual hosts, and manage the hosts in remote.Once the docker installed, you should get a few commands start from docker and able to start your docker service, and launch your docker container. You can check the official documentation to get the latest news and some detail explanations.
There is an official instruction from this link. You will control the dockers using remote tool
IF your operating system is mac OS, Windows, FreeBSD, and so on, you are supposed to install a virtual machine, start a special configured Linux system which hosts a Docker service. IF your operating system is Linux, you are supposed to install docker service directly. The principle of setting up a docker environment is pretty straightforward. (from Wikipedia)īasically, you can treat docker as a lightweight virtual machine hosted on Linux with a pretty high performance. Docker uses the resource isolation features of the Linux kernel such as cgroups and kernel namespaces, and a union-capable file system such as OverlayFS and others to allow independent "containers" to run within a single Linux instance, avoiding the overhead of starting and maintaining virtual machines (VMs). #Docker mac os companity software
Install Dockerĭocker is a software technology providing operating-system-level virtualization also known as containers, promoted by the company Docker, Inc. While, you can still start all the Hadoop related services except Zeppelin, even if you only reserve 4GB for the virtual machine. You are supposed to reserve at least 4 GB RAM for Docker, and some other memory for the host machine. You should have enough system resource if you are planning to start a container in your local OS. If your can meet the minimum requirement, the system could randomly kill one or a few process due to resource limitation, which causes a lot of strange errors which is even unable to reproduce.ĭON'T TRY TO DO THAT. # install postgres from the private registryĭocker run -p 5432:5432 -name postgres -d 10.2.4.Since this docker image integrated a lot of related services for the course, it requires at least 4GB RAM for this virtual machine. # search postgres from the private registry
It can be done via the docker client installed in your OS-X machine. Now you can search, pull, push the images in your private registry from you host OS-X machine. Restart docker server(service) from boot2docker sudo /etc/init.d/docker restart 4. Please note that private registry host is in our local environment(IP - 10.2.4.201)ģ. Now your boot2docker profile file looks like below. If your private registry doesn't supports SSL(HTTPS), add following entry(insecure-registry) to /var/lib/boot2docker/profileĮcho 'EXTRA_ARGS="-insecure-registry "' | sudo tee -a /var/lib/boot2docker/profile. ssh to boot2docker VM # first need to up the boot2docker VM In order to add private docker registry, we ssh to boot2docker VM add registry entry into itġ. We use boot2docker light weight linux virtual machine. In order to use docker in OS-X we have to install linux virtual machine and run the docker server on it. After setting up private registry you can push, pull images to and from it. #Docker mac os companity code
You can take the docker registry code and host in your own local server, in order to use as a private docker registry. Docker registry is open source project - docker-registry. You can just create new image with upgraded java, replace the existing image in production with newly created image. #Docker mac os companity upgrade
Another advantage with docker and docker registry is you don't need manually upgrade your production environment(for an instance upgrade java in production). From production machine you can pull it. You can build a docker image from your development machine push it to docker registry. 
Traditional way of production deployment is, you need to manually deploy all your stuffs(source codes, environment upgrades etc.) to production environment (by using shell scripts or other kind of mechanism).These pushed images can be downloaded in another environment.After building images you can upload/push your images to the registry.
You can take/pull libraries, apps from registry to build your images,. It is an open-source project and can be found at If simply says, the Docker registry is Docker’s in-build way to share images #Docker mac os companity download
To solve this problem docker introduces docker-registryĭocker registry allows you to upload, download and share your own images
Where does the apps and libraries comes from. To build your images you use various apps, libraries etc. You can build your own images(with multiple containers) by using docker.
