Coder turns your cloud into a fleet of remote development servers.

</p>

**Code more**

- Build and test faster
  - Leveraging cloud CPUs, RAM, network speeds, etc.
- Access your environment from any place on any client (even an iPad)
- Onboard instantly then stay up to date continuously

**Manage less**

- Ensure your entire team is using the same tools and resources
  - Rollout critical updates to your developers with one command
- Automatically shut down expensive cloud resources
- Keep your source code and data behind your firewall

## How it works

Coder workspaces are represented with Terraform. But, no Terraform knowledge is
required to get started. We have a database of pre-made templates built into the
product.

Coder workspaces don't stop at compute. You can add storage buckets, secrets, sidecars
and whatever else Terraform lets you dream up.

## IDE Support

You can use any Web IDE ([code-server](https://github.com/coder/code-server), [projector](https://github.com/JetBrains/projector-server), [Jupyter](https://jupyter.org/), etc.), [JetBrains Gateway](https://www.jetbrains.com/remote-development/gateway/), [VS Code Remote](https://code.visualstudio.com/docs/remote/ssh-tutorial) or even a file sync such as [mutagen](https://mutagen.io/).

## Installing Coder

We recommend installing [the latest
release](https://github.com/coder/coder/releases) on a system with at least 1
CPU core and 2 GB RAM:

1. Download the release appropriate for your operating system
1. Unzip the folder you just downloaded, and move the `coder` executable to a
   location that's on your `PATH`

> Make sure you have the appropriate credentials for your cloud provider (e.g.,
> access key ID and secret access key for AWS).

You can set up a temporary deployment, a production deployment, or a system service:

- To set up a **temporary deployment**, start with dev mode (all data is in-memory and is
  destroyed on exit):

  ```bash
  coder server --dev
  ```

- To run a **production deployment** with PostgreSQL:

  ```bash
  CODER_PG_CONNECTION_URL="postgres://<username>@<host>/<database>?password=<password>" \
      coder server
  ```

- To run as a **system service**, install with `.deb` (Debian, Ubuntu) or `.rpm`
  (Fedora, CentOS, RHEL, SUSE):

  ```bash
  # Edit the configuration!
  sudo vim /etc/coder.d/coder.env
  sudo service coder restart
  ```

> Use `coder --help` to get a complete list of flags and environment
> variables.

See the [installation guide](./docs/install.md) for additional ways to deploy Coder.

## Creating your first template and workspace

In a new terminal window, run the following to copy a sample template:

```bash
coder templates init
```

Follow the CLI instructions to modify and create the template specific for your
usage (e.g., a template to **Develop in Linux on Google Cloud**).

Create a workspace using your template:

```bash
coder create --template="yourTemplate" <workspaceName>
```

Connect to your workspace via SSH:

```bash
coder ssh <workspaceName>
```

## Modifying templates

You can edit the Terraform template using a sample template:

```sh
coder templates init
cd gcp-linux/
vim main.tf
coder templates update gcp-linux
```
