# @adp-psych/container-tools

Tools for using containers for psychology experiments.

## Usage

### Installation

Install the package from [npm](https://www.npmjs.com/)
(requires [Node.js](https://nodejs.org/)):

```sh
npm install --save-dev @adp-psych/container-tools
```

### Dependencies

These tools depend on the following software:

- [**podman**](https://podman.io/):
  A tool for running [OCI](https://opencontainers.org/) containers.
  [\[Installation instructions\]](https://podman.io/getting-started/installation.html)

- [**buildah**](https://buildah.io/):
  A tool for building [OCI](https://opencontainers.org/) images.
  [\[Installation instructions\]](https://github.com/containers/buildah/blob/master/install.md)

- [**doctl**](https://docs.digitalocean.com/reference/doctl/):
  The [DigitalOcean](https://www.digitalocean.com/) command-line interface.
  [\[Installation instructions\]](https://docs.digitalocean.com/reference/doctl/how-to/install/)

- [**kubectl**](https://kubernetes.io/docs/tasks/tools/#kubectl):
  The [Kubernetes](https://kubernetes.io/) command-line interface.
  [\[Installation instructions\]](https://kubernetes.io/docs/tasks/tools/#kubectl)

- [**Helm**](https://helm.sh/):
  The [Kubernetes](https://kubernetes.io/) package manager.
  [\[Installation instructions\]](https://helm.sh/docs/intro/install/)

The above software must be installed and available via the system path
for these tools to work.

### Accounts

These tools require you to have a [DigitalOcean](https://www.digitalocean.com/)
account to host your experiments and a container registry account to host your
containers (e.g., [Quay.io](https://quay.io/)).

#### DigitalOcean

[Sign up for a DigitalOcean account](https://cloud.digitalocean.com/registrations/new)
and
[create a personal access token](https://docs.digitalocean.com/reference/api/create-personal-access-token/).
I recommend creating a separate personal access token for each computer that
will have access to your DigitalOcean account, and naming each token after
the computer that will use it.

Configure doctl to access your account (replace `$TOKEN` with your token):

```sh
doctl auth init -t "$TOKEN"
```

Then
[create another personal access token](https://docs.digitalocean.com/reference/api/create-personal-access-token/)
named `ExternalDNS` for
[ExternalDNS](https://github.com/kubernetes-sigs/external-dns) to use.

#### Quay.io

[Create a Quay.io account](https://quay.io/signin/).

Configure podman to access your account:

```sh
podman login quay.io
```
