gofabric8

gofabric8 installer

gofabric8 is used to validate & deploy fabric8 components on to your Kubernetes or OpenShift environment

Find more information at http://fabric8.io.

Getting started

Install / Update & run

Get the latest gofabric8 or use the following script to download it.

curl -sS https://get.fabric8.io/download.txt | bash

add '~/.fabric8/bin' to your path so you can execute the new binaries, for example: edit your ~/.zshrc or ~/.bashrc and append to the end of the file

export PATH=$PATH:~/.fabric8/bin
source ~/.zshrc or ~/.bashrc

minikube

gofabric8 install

minishift

NOTE currently the latest version of minishift that fabric8 currently runs on is 0.9.0

gofabric8 install --minishift

Install the fabric8 microservices platform

To install the fabric8 microservices platform then run the following:

gofabric8 deploy

If you are deploying to a remote OpenShift instance make sure to set the domain so we can generate Toutes to access applications

gofabric8 deploy --domain=your.domain.io

Reusing the Docker daemon

When developing locally and using a single VM its really handy to reuse the Docker daemon inside the VM; as this means you don't have to build on your host machine and push the image into a docker registry - you can just build inside the same docker daemon as minikube which speeds up local experiments.

To be able to work with the docker daemon on your mac/linux host use the docker-env command in your shell:

eval $(gofabric8 docker-env)

you should now be able to use docker on the command line on your host mac/linux machine talking to the docker daemon inside the minikube VM:

docker ps

Remember to turn off the imagePullPolicy:Always, as otherwise kubernetes won't use images you built locally.

Run different versions

When deploying, by default the latest release version is used. In order to deploy a specific version you can use the various--version-xxxx flags as detailed under

gofabric8 deploy help
