# Skydive Operator (WIP)
4+
5+
This is a simple operator to deploy skydive analyzer and agents.
6+
7+
<!-- GETTING STARTED -->
8+
9+
## Getting Started
10+
11+
To set up this operator follow the instructions below:
12+
13+
### Prerequisites
14+
15+
* Make sure you have golang installed on your machine, The go-lang version that this operator was built on is go1.15.7
16+
darwin/amd64
17+
18+
* An openshift cluster
19+
* If you don't have an openshift cluster you may locally install one
20+
using [kind](https://kind.sigs.k8s.io/docs/user/quick-start/)
21+
22+
### Installation
23+
24+
1. If you're running a kind cluster the following commands won't work for you and you will have to modify the project
25+
namespace in the next part
26+
27+
```zsh
28+
oc adm new-project --node-selector='' skydive
29+
oc project skydive
30+
```
31+
32+
2. Run this to grant privileges to your user (#TODO this is maybe not needed)
33+
34+
```zsh
35+
oc adm policy add-scc-to-user privileged -z default
36+
oc adm policy add-cluster-role-to-user cluster-reader -z default
37+
```
38+
39+
3. Clone this repo into your $GOPATH/src folder
40+
4. From skydive-operator folder run:
41+
42+
```bash
43+
make manifests
44+
kubectl create -f config/crd/bases
45+
kubectl create -f config/samples/skydive_v1beta1_skydiveanalyzer.yaml
46+
kubectl create -f config/samples/skydive_v1beta1_skydiveagents.yaml
47+
make run
48+
```
49+
50+
You might need to install some golang packages
51+
(#TODO make sure to see what my IDE auto installed for me)
