# Podman Examples

```
podman pull imagename

podman run imagename

Example:

podman pull hello-world

podman run hello-world

podman container ls

podman container ls -a

podman image ls


```

Let's try to launch Neo4J

**Method 1**

```
docker pull neo4j

docker run neo4j
```

**Method 2**

```
mkdir neo4j
cd neo4j
mkdir data
mkdir logs
```

**Mac/Linux**

```
podman run -it -d  --name myneo --publish=7474:7474 --publish=7687:7687 --volume=$PWD/data:/data --volume=$PWD/logs:/logs neo4j:latest
```

**Windows**

```
podman run -it -d  --name myneo --publish=7474:7474 --publish=7687:7687 -v data:/data -v logs:/logs neo4j:latest
```

Browser

<http://localhost:7474\\>
\
user: neo4j

pwd: neo4j

when it prompts change new pwd

**To log into the Container**

```
podman exec -it containername bash
```

To view the Log messages

```
podman logs containername
```

**Custom Image**

Create a file  "Dockerfile"

```
# Use an official Ubuntu base image
FROM ubuntu:latest

# Install nginx
RUN apt-get update && apt-get install -y nginx

# Expose port 80
EXPOSE 80

# Run nginx
CMD ["nginx", "-g", "daemon off;"]
```

Build an image

```
podman build -t gc-nginx-image .
```

Run the container using above image

```
podman run --name my-web-app -d -p 8080:80 gc-nginx-image
```

Open browser and navigate to <http://localhost:8080>

Python Example

main.py

```

def add(x, y):
    return x + y

def subtract(x, y):
    return x - y

def multiply(x, y):
    return x * y

def divide(x, y):
    if y == 0:
        return "Error! Division by zero."
    return x / y

if __name__ == "__main__":
    print(add(1, 2))
    print(subtract(1, 2))
    print(multiply(1, 2))
    print(divide(1, 2))

```

Dockerfile

```dockerfile
FROM python:3.9-slim

WORKDIR /app

COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt

COPY main.py .

CMD ["python", "./main.py"]

```

requirements.txt

```
faker
```

Build (default it uses Dockerfile, but can customized with -f parameter)

```
podman build -t mycalc .
```

```
podman build -t mycalc -f pathtoDockerfile
```

Run

```
podman run --name gccalc mycalc
```
