# Pulumi Nginx Server in a instance (GCP)
4+
5+
Starting point for building the Pulumi nginx server sample in Google Cloud Platform.
6+
7+
## Running the App
8+
9+
1. Create a new stack:
10+
11+
```
12+
$ pulumi stack init gcp-instance-nginx
13+
```
14+
15+
2. Configure Python environment:
16+
```
17+
virtualenv -p python3 venv
18+
source venv/bin/activate
19+
pip install pulumi_gcp
20+
```
21+
22+
3. Configure the project:
23+
24+
```
25+
$ export GOOGLE_PROJECT=cncf-230209; export GOOGLE_REGION=asia-east1; export GOOGLE_ZONE=asia-east1-a;
26+
$ export GOOGLE_CREDENTIALS=YOURGCPCREDENTIALS
27+
```
28+
29+
4. Run `pulumi up` to preview and deploy changes:
30+
31+
```
32+
