RHEL_Openfaas

Building OpenFaas

The instructions provided below specify the steps to build OpenFaas and OpenFaas Cloud components on Linux on IBM Z for following distributions:

RHEL (7.6)

General Notes:

When following the steps below please use a super user unless otherwise specified.
A directory /<source_root>/ will be referred to in these instructions, this is a temporary writable directory anywhere you'd like to place it.

Prerequisites

Docker 18.06
Kubernetes Cluster v1.13.2 Setup

Step 1: Install dependencies

  export SOURCE_ROOT=/<source_root>/
  yum install -y make curl

Install Go 1.10.4

wget https://raw.githubusercontent.com/linux-on-ibm-z/scripts/master/Go/build_go.sh
bash build_go.sh -v 1.10.4
mkdir $SOURCE_ROOT/go
export GOPATH=$SOURCE_ROOT/go

Step 2: Build OpenFaas Components

Deploy OpenFaaS Cloud using ofc-bootstrap tool

Note: These guidelines supplement ofc-bootstrap instructions. Before you can deploy OpenFaas Cloud using ofc-bootstap make sure your environment is ready for deployment.
- Ensure you have a private Docker registry setup to hold OpenFaas functions deployed by the OpenFaas Cloud pipeline.
- Gitlab acount to host your OpenFaaS functions and appropriate Hooks to trigger the build.
- An internal server to serve required binaries and Helm charts for the installation
- A DNS server as required by OpenFaas Cloud installation
Once all the required images have been built by preceding steps and init.yaml file has been created as per ofc-bootstarp instructions, you can start the deployment as follows:
```
cd $GOPATH/src/github.com/openfaas-incubator/ofc-bootstrap/
./ofc-bootstrap -yaml=init.yaml
```
