You can start an empty Java container using Docker image for Java containersįabric8 uses fabric8/fabric8-java image to create dockerized Java containers. like a child/ssh/openshift/cloud container). Other than that the container should appear like any other container (e.g. Once you've created a container, it should appear if you type the following on the command line: docker ps You just need to choose a container name and one or more profiles and away you go. Now when you try to create a container in the web console (hawtio) it will by default choose the docker container provider. Note that the docker profile needs to be added to the container you'll use to create new docker containers (which would be the root container if you are using your laptop).

So create a fabric using the following command (feel free to use a different username / password and different IP address for the current machine ): fabric:create -new-user admin -new-user-password admin -wait-for-provisioning -resolver manualip -m 192.168.42.1 -profile docker You need to be careful to ensure that any docker container can connect to the IP/host names you are using to create your ZooKeeper cluster. Using Fabric8 and Dockerįabric8 lets you create containers using the docker container provider which under the covers uses the Docker Remote API to create/start/stop/kill containers. The FABRIC8_PROFILES environment variable just enables the docker profile on startup so you can create docker containers via the web console and can use the docker web tooling (based on dockerui). on OS X or Windows) where you often cannot communicate with your host machine's host name from inside the docker container. The FABRIC8_GLOBAL_RESOLVER environment variable ensures that the IP resolver will be used which is useful if you are not using linux and so are using Docker via some virtualisation (e.g.

In addition it is useful to set these 2 environment variables: export FABRIC8_GLOBAL_RESOLVER=localip

To locally install the main 3 docker images for fabric8 type this: docker pull fabric8/fabric8 The default docker container image for fabric8 is fabric8/fabric8 Once installed you should be able to run commands like: docker ps Anyone with access to the Docker Remote API effectively has complete control of the Docker host. Security Warningīinding the Docker service to a public-facing network interface is a major security risk.

If running on Linux, please refer to docker documentation on how to bind Docker to a host/port or a Unix socket. This can be easily done by running: $(boot2docker shellinit)

This means setting additional environment variables. TLS is enabled on the docker service in boot2docker 1.3 and later. Fabric8 uses the DOCKER_HOST environment variable to know where the Docker Remote API is located. on a Mac the value of DOCKER_HOST is often something like tcp://192.168.59.103:2375. From docker 1.0 or later this is usually something like: export DOCKER_HOST=tcp://$(boot2docker ip 2>/dev/null):2375Į.g. The DOCKER_HOST environment variable should point to the URL to connect to docker. To be able to try Docker with Fabric8 you need to install docker on the machine you are running a fabric8 container. So Docker makes it super easy to distribute containers and create them quickly. It basically re-uses a single host Linux installation and lets you run separate docker containers in what appears to be a sandboxed virtual machine when in reality it's using various Linux technologies like lightweight containers, namespaces, process groups and copy-on-write file systems to simulate virtualiastion. Fabric8 can use docker to create new containers allowing you to reuse the power of docker.ĭocker has all the benefits of virtualisation but without any of the I/O, CPU or memory performance costs.
