7	Use this skill when:
8	- Deploying applications to OpenShift clusters
9	- Using OpenShift-specific features (Routes, BuildConfigs)
10	- Managing projects and RBAC in OpenShift
11	- Implementing S2I (Source-to-Image) builds
12	- Working with OpenShift Operators
13
14	## Prerequisites
15
16	- OpenShift cluster access
17	- oc CLI installed
18	- Basic Kubernetes knowledge
19
20	## CLI Basics
21
22	### Authentication
23
24	```bash
25	# Login to cluster
26	oc login https://api.cluster.example.com:6443 -u admin -p password
27
28	# Login with token
29	oc login --token=sha256~xxxx --server=https://api.cluster.example.com:6443
30
31	# Check current context
32	oc whoami
33	oc whoami --show-server
34	oc whoami --show-context
35
36	# Logout
37	oc logout
38	```
39
40	### Project Management
41
42	```bash
43	# Create project (namespace)
44	oc new-project myapp --display-name="My App" --description="My Application"
45
46	# Switch project
47	oc project myapp
48
49	# List projects
50	oc projects
51
52	# Delete project
53	oc delete project myapp
54	```
55
56	## Deploying Applications
57
58	### From Image
59
60	```bash
61	# Deploy from container image
62	oc new-app --image=nginx:latest --name=webserver
63
64	# Deploy from Docker Hub
65	oc new-app docker.io/library/nginx:latest
66
67	# Deploy with environment variables
68	oc new-app myimage:latest \
69	-e DATABASE_URL=postgres://localhost/db \
70	-e APP_ENV=production
71	```
72
73	### From Source (S2I)
74
75	```bash
76	# Deploy from Git repository
77	oc new-app https://github.com/org/myapp.git
78
79	# Specify builder image
80	oc new-app nodejs:18~https://github.com/org/nodejs-app.git
81
82	# With context directory
83	oc new-app https://github.com/org/monorepo.git \
84	--context-dir=backend \
85	--name=backend-api
86	```
87
88	### From Template
89
90	```bash
91	# List available templates
92	oc get templates -n openshift
93
94	# Deploy from template
95	oc new-app postgresql-persistent \
96	-p POSTGRESQL_USER=user \
97	-p POSTGRESQL_PASSWORD=secret \
98	-p POSTGRESQL_DATABASE=mydb
99	```
100
101	## Routes
102
103	### Creating Routes
104
105	```yaml
106	apiVersion: route.openshift.io/v1
107	kind: Route
108	metadata:
109	name: myapp
110	spec:
111	host: myapp.apps.cluster.example.com
112	to:
113	kind: Service
114	name: myapp
115	weight: 100
116	port:
117	targetPort: 8080
118	tls:
119	termination: edge
120	insecureEdgeTerminationPolicy: Redirect
121	```
122
123	```bash
124	# Create route via CLI
125	oc expose svc/myapp
126
127	# Create with custom hostname
128	oc create route edge myapp \
129	--service=myapp \
130	--hostname=myapp.apps.cluster.example.com
131
132	# Create passthrough route (TLS termination at pod)
133	oc create route passthrough myapp-secure --service=myapp
134	```
135
136	### A/B Testing
