Instructions posted in the fn project page:
#1 Setup a VM running OL7.2 with 50GB
Preferably pick OL72 over OL68 as fn require docker > 17.5
#2 Setup security policy (OL7)
# setenforce permission
#3 Install docker (root)
Follow the instructions posted in the documentation.
Update /etc/yum.repos.d/public-yum-ol7.repo to enable the ol7_addons then
# yum install docker-engine wget tree # chkconfig docker on # yum update # service docker start
#4 Install fn (as root)
curl -LSs https://raw.githubusercontent.com/fnproject/cli/master/install | sh
#5 Create a runtime user and add it to the docker group
# useradd -g 500 -d /home/oracle oracle # sudo usermod -a -G docker oracle
#6 Login as oracle and start the fn server
$ fn start
#5 Login again as oracle in a second window and configure a demo project
$ mkdir project $ cd project $ fn init --runtime go hello $ cd hello $ fn run $ fn deploy --app myapp --local $ fn invoke myapp hello
Update the file func.go, changing Hello with bonjour, deploy and test again
$ fn deploy --app myapp --local
$ fn invoke myapp hello
{"message":"Bonjour World"}
