# MRSK
MRSK deploys web apps anywhere from bare metal to cloud VMs using Docker with zero downtime. It uses the dynamic reverse-proxy Traefik to hold requests while the new application container is started and the old one is stopped. It works seamlessly across multiple hosts, using SSHKit to execute commands. It was built for Rails applications, but works with any type of web app that can be containerized with Docker.

8. Ensure your app responds with `200 OK` to `GET /up`.
9. Start a new container with the version of the app that matches the current git version hash.
10. Stop the old container running the previous version of the app.

Voila! All the servers are now serving the app on port 80. If you're just running a single server, you're ready to go. If you're running multiple servers, you need to put a load balancer in front of them.
## Vision
In the past decade+, there's been an explosion in commercial offerings that make deploying web apps easier. Heroku kicked it off with an incredible offering that stayed ahead of the competition seemingly forever. These days we have excellent alternatives like Fly.io and Render. And hosted Kubernetes is making things easier too on AWS, GCP, Digital Ocean, and elsewhere. But these are all offerings that have you renting computers in the cloud at a premium. If you want to run on your own hardware, or even just have a clear migration path to do so in the future, you need to carefully consider how locked in you get to these commercial platforms. Preferably before the bills swallow your business whole!

If you want to run on our own hardware, or even just have a clear migration path to do so, you need to carefully consider how locked in you get to these commercial platforms. Preferably before the bills swallow your business whole!
MRSK seeks to bring the advance in ergonomics pioneered by these commercial offerings to deploying web apps anywhere. Whether that's low-cost cloud options without the managed-service markup from the likes of Digital Ocean, Hetzner, OVH, etc, or it's your own colocated bare metal. To MRSK, it's all the same. Feed the config file a list of IP addresses with vanilla Ubuntu servers that have seen no prep beyond an added SSH key, and you'll be running in literally minutes.

This approach gives you enormous portability. You can have your web app deployed on several clouds at ease like this. Or you can buy the baseline with your own hardware, then deploy to a cloud before a big seasonal spike to get more capacity. When you're not locked into a single provider from a tooling perspective, there are a lot of compelling options available.

Ultimately, MRSK is meant to compress the complexity of going to production using open source tooling that isn't tied to any commercial offering. Not to zero, mind you. You're probably still better off with a fully managed service if basic Linux or Docker is still difficult, but as soon as those concepts are familiar, you'll be ready to go with MRSK.

You're probably still better off with a fully managed service if basic Linux or Docker is still difficult, but from an early stage when those concepts are familiar.
## Why not just run Capistrano, Kubernetes or Docker Swarm?
MRSK basically is Capistrano for Containers, without the need to carefully prepare servers in advance. No need to ensure that the servers have just the right version of Ruby or other dependencies you need. That all lives in the Docker image now. You can boot a brand new Ubuntu (or whatever) server, add it to the list of servers in MRSK, and it'll be auto-provisioned with Docker, and run right away. Docker's layer caching also speeds up deployments with less mucking about on the server. And the images built for MRSK can be used for CI or later introspection.

Kubernetes is a beast. Running it yourself on your own hardware is not for the faint of heart. It's a fine option if you want to run on someone else's platform, either transparently [like Render](https://thenewstack.io/render-cloud-deployment-with-less-engineering/) or explicitly on AWS/GCP, but if you'd like the freedom to move between cloud and your own hardware, or even mix the two, MRSK is much simpler. You can see everything that's going on, it's just basic Docker commands being called.
Docker Swarm is much simpler than Kubernetes, but it's still built on the same declarative model that uses state reconciliation. MRSK is intentionally designed around imperative commands, like Capistrano.
Ultimately, there are a myriad of ways to deploy web apps, but this is the toolkit we're using at [37signals](https://37signals.com) to bring [HEY](https://www.hey.com) [home from the cloud](https://world.hey.com/dhh/why-we-re-leaving-the-cloud-654b47e0) without losing the advantages of modern containerization tooling.

### Using a generated .env file
#### 1Password as a secret store
If you're using a centralized secret store, like 1Password, you can create `.env.erb` as a template which looks up the secrets. Example of a .env.erb file:
```erb
<% if (session_token = `op signin --account my-one-password-account --raw`.strip) != "" %># Generated by mrsk envify
GITHUB_TOKEN=<%= `gh config get -h github.com oauth_token`.strip %>
MRSK_REGISTRY_PASSWORD=<%= `op read "op://Vault/Docker Hub/password" -n --session #{session_token}` %>
RAILS_MASTER_KEY=<%= `op read "op://Vault/My App/RAILS_MASTER_SECRET" -n --session #{session_token}` %>
MYSQL_ROOT_PASSWORD=<%= `op read "op://Vault/My App/MYSQL_ROOT_PASSWORD" -n --session #{session_token}` %>
<% else raise ArgumentError, "Session token missing" end %>
```
This template can safely be checked into git. Then everyone deploying the app can run `mrsk envify` when they setup the app for the first time or passwords change to get the correct `.env` file.
If you need separate env variables for different destinations, you can set them with `.env.destination.erb` for the template, which will generate `.env.staging` when run with `mrsk envify -d staging`.
#### Bitwarden as a secret store
If you are using open source secret store like bitwarden, you can create `.env.erb` as a template which looks up the secrets.
You can store `SOME_SECRET` in a secure note in bitwarden vault.
```
$ bw list items --search SOME_SECRET | jq
? Master password: [hidden]
[
{
"object": "item",
"id": "123123123-1232-4224-222f-234234234234",

"creationDate": "2022-11-07T03:16:05.828Z",
"deletedDate": null
}
]
```
and extract the `id` of `SOME_SECRET` from the `json` above and use in the `erb` below.
Example `.env.erb` file:
```erb
<% if (session_token=`bw unlock --raw`.strip) != "" %># Generated by mrsk envify
SOME_SECRET=<%= `bw get notes 123123123-1232-4224-222f-234234234234 --session #{session_token}` %>
<% else raise ArgumentError, "session_token token missing" end %>
```
