#### A lightweight caching proxy for the Snap Store

Arcus is a lightweight proxy to the Snap Store for your snap devices. Once
installed and configured, your devices can be configured to talk to the Snap
Store via Arcus. Arcus caches downloaded snaps, and acts as a single point
of egress from your network.

# Quickstart

Install the ols-arcus snap and run:

```
 ols-arcus.arcus register https://my.arcus.internal me@example.com
```

to register and configure your arcus instance. After that's done, client device
configuration instructions will be printed out. Run

```
 ols-arcus.arcus register --help
```

for details on the `register` command arguments.

# TLS

`tls` sub-command can be used to manage the TLS certificate used by arcus to
encrypt traffic it receives from client devices. The registration command,
generates a self signed certificate for arcus, if the registered arcus
location is an HTTPS location. This certificate can be changed or exported
as needed using the `tls` command. `tls --off` and `tls --on` can be used to
disable/enable TLS.

# Status

`status` command will print out the most essential information about the running
Arcus instance.

# Configuration

`configure` command can be used for finer grade management of configuration
options.

## Enable snaps on CentOS and install ols-arcus

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.

Snaps are discoverable and installable from the [Snap Store](https://snapcraft.io/store), an app store with an audience of millions.

### Enable snapd

Snap is available for [CentOS 7.6+](https://snapcraft.io/install/ols-arcus/centos), and Red Hat Enterprise Linux 7.6+, from the [Extra Packages for Enterprise Linux](https://fedoraproject.org/wiki/EPEL) (EPEL) repository. The EPEL repository can be added to your system with the following command:

```
sudo yum install epel-release
```

Snap can now be installed as follows:

```
sudo yum install snapd
```

Once installed, the *systemd* unit that manages the main snap communication socket needs to be enabled:

```
sudo systemctl enable --now snapd.socket
```

To enable *classic* snap support, enter the following to create a symbolic link between `/var/lib/snapd/snap` and `/snap`:

```
sudo ln -s /var/lib/snapd/snap /snap
```

Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
