# Running a pod using a container or docker file

This tutorial covers the following end-to-end tasks a user requires to run a pod from a container or docker file:

- Building an image
- Creating a container
- Creating and running a pod

When creating a container, you can set the following configurations:

- With **Basic** configuration, you have the option to:

  - Define volumes to configure a persistent storage location. For this, you must set up a host directory and then mount this directory to a container. You can keep your application data intact in your host directory even after your container is stopped or failed.
  - Define port mapping to create an externally accessible container. For this, you must map a host port with the container port. After this mapping, any requests to port on the host are forwarded to port in the container.

  - Select a file containing environment variables for your container. This file contains data in the `key=value` format.

- With **Advanced** configuration, you have the option of:

  - Automatic removal of container
  - Specifying ID of the user who can run a container
  - Selecting a restart policy that defines whether a container should restart on exit

- With **Networking** configuration, you have the option of defining:

  - A container host name
  - A custom DNS server
  - Additional hosts
  - The networking mode for a container

- With **Security** configuration, you have the option to:
  - Secure you container resources
  - Make container root filesystem read-only
  - Add or drop security capabilities
  - Specify a namespace to restrict the usage of containers to a group of users with defined privileges and ownership

## Before you begin

- [Installed Podman Desktop application](/docs/installation)
- [A Podman machine](/docs/podman/creating-a-podman-machine)
- A docker or container file to use. Create a docker file using the following code, if you do not have one on your machine:

```dockerfile
# syntax=docker/dockerfile:1

ARG NODE_VERSION
ARG ALPINE_VERSION

FROM node:${NODE_VERSION}-alpine${ALPINE_VERSION} AS base
WORKDIR /src

FROM base AS build
COPY package*.json ./
RUN npm ci
RUN npm run build

FROM base AS production
COPY package*.json ./
RUN npm ci --omit=dev && npm cache clean --force
COPY --from=build /src/dist/ .
CMD ["node", "app.js"]
```

## Building an image

1. Click **Containers** in the left navigation pane.
2. Click **Create**.

3. On the **Build image from Containerfile** page, provide the following details:

   - Containerfile path: Select the path where the container or docker file is placed.
   - Build context directory: The field automatically picks up the context directory based on the file path.
   - Image name: Enter the image name, if required.
   - Build arguments: Pass the required arguments to build the image. This example uses arguments, such as `NODE_VERSION` and `ALPINE_VERSION`
   - Platform: Change the platform on which you want to build the image. The default platform is Intel and AMD x86_64 systems.

4. Click **Build**. The image starts to build.
5. Click **Done** once the image is built successfully.
6. View the newly created image on the **Images** page.

## Creating a container

1. Click **Images** in the left navigation pane.
2. Click the **Run Image** icon corresponding to the image you want to run. The **Create a container from image page** opens.
