From the VM details page, click on the subnet: We'll need to open some ports in our firewall and security list to expose the Rocket.Chat application to the web, so let's start by add some ingress rules to our VM security list in the Oracle Cloud dashboard. In my case, I'm going to use the URL, so I'll add an A record with my DNS host to point at my VM's IP address:įollow the directions of your particular hosting provider to point a domain (or subdomain) at your VMs IP address and you're ready to SSH in to the VM and continue the process. Rocket.Chat will give us free SSL out of the box by creating a reverse proxy with Caddy which makes use of Let’s Encrypt to automatically provide you SSL protection for your communications. The first thing we'll need to do is associate our VM's public IP address with a domain name. If you skip this step your install will certainly fail. We'll need to take care of a few items before we can start the Rocket.Chat install. You can now SSH in to the machine using the private key associated with the public key you uploaded when you created the VM. We'll need this as we move on in this tutorial. Copy the public IP address that has been assigned to the VM. Next, choose a public key file that has an associated private key that can be used to access this VM after it is created.Ĭlick on 'Create' and you'll be directed to the instance details page and the VM will be in a 'Provisioning' state:Īfter a short wait the instance will become 'Available'. Make sure to check 'Assign a public IP address' otherwise you will not be able to access the VM via the web! Same thing goes for the instance shape - choose the 'Always Free Eligible' option. If necessary, click 'Show Shape, Network, Storage Options' and make sure the Availability Domain and Instance Type are both 'Always Free Eligible'. The instructions below will be for the default OS which is Oracle Linux, so it's probably best to stick with the default. Give your instance a name and optionally change the image source. Once you've signed up for your free account, log in and head to the Oracle Cloud dashboard. You'll need to have a credit card on file, but you'll absolutely never be charged if you stick to the "always free" services. If you're new to Oracle Cloud, you'll have to first sign up for a completely free account. Use Oracle Object Storage For Upload Storage.Configure Oracle IDCS As An Auth Provider.We're going to do the following (but feel free to skip ahead if you know how to create a VM already): Today we're going to look at one of the major players in the free, open source, team-based communication and collaboration market: Rocket.Chat. That's right, with the Oracle Cloud "always free" tier you can get up and running for absolutely nothing. And if you've read any of my other blog posts recently then you'll know what I'm about to tell you. So that means for the price of a VM, some storage and bandwidth you can get a team chat solution online quickly and easily. There are a handful of really nice alternatives out there that are both free and open source if you're willing to install it yourself and maintain the installation (it's not hard - trust me). But that doesn't mean you're stuck paying licensing fees for your organization. There are a few major players in the world of communications apps, but most of them aren't free or open source. Conferences, organizations, colleges, schools - you name it, and I'm willing to bet they are using something to keep in touch. Just about every single company these days uses some sort of chat application for team-based communications.
