How to update Matrix?
|
|
=====================
|
|
|
|
## 1. Build the new containers
|
|
|
|
Often, I update Riot Web and Synapse at the same time.
|
|
|
|
|
|
* Open `app/docker-compose.yml` and locate `riot` (the Element Web service) and `synapse` (the Matrix Synapse server). There are two things you need to do for each service:
|
|
|
|
* Set the `VERSION` argument to the target service version (e.g. `1.26.0` for Synapse). This argument is then used to template the Dockerfile.
|
|
|
|
The `VERSION` value should match a github release, the link to the corresponding release page is put as a comment next to the variable in the compose file;
|
|
|
|
* Tag the image with a new incremented version tag. For example: `superboum/amd64_riotweb:v17` will become `superboum/amd64_riotweb:v18`.
|
|
|
|
We use the docker hub to store our images. So, if you are not `superboum` you must change the name with your own handle, eg. `john/amd64_riotweb:v18`. This requires that you registered an account (named `john`) on https://hub.docker.com.
|
|
|
|
|
|
So, from now we expect you have:
|
|
|
|
* changed the `VERSION` value and `image` name/tag of `riot`
|
|
* changed the `VERSION` value and `image` name/tag of `synapse`
|
|
|
|
From the `/app` folder, you can now simply build and push the new images:
|
|
|
|
```bash
|
|
docker-compose build riot synapse
|
|
```
|
|
|
|
And then send them to the docker hub:
|
|
|
|
```
|
|
docker-compose push riot synapse
|
|
```
|
|
|
|
Don't forget to commit and push your changes before doing anything else!
|
|
|
|
## 2. Deploy the new containers
|
|
|
|
Now, we will edit the deployment file `app/im/deploy/im.hcl`.
|
|
|
|
Find where the image is defined in the file, for example Element-web will look like that:
|
|
|
|
|
|
```hcl
|
|
group "riotweb" {
|
|
count = 1
|
|
|
|
task "server" {
|
|
driver = "docker"
|
|
config {
|
|
image = "superboum/amd64_riotweb:v17"
|
|
port_map {
|
|
web_port = 8043
|
|
}
|
|
```
|
|
|
|
And replace the `image =` entry with its new version created above.
|
|
Do the same thing for the `synapse` service.
|
|
|
|
Now, you need a way to access the cluster to deploy this file.
|
|
To do this, you must bind nomad on your machine through a SSH tunnel.
|
|
Check the end of [the parent `README.md`](../README.md) to do it.
|
|
If you have access to the Nomad web UI when entering http://127.0.0.1:4646
|
|
you are ready to go.
|
|
|
|
You must have installed the Nomad command line tool on your machine (also explained in [the parent `README.md`](../README.md)).
|
|
|
|
Now, on your machine and from the `app/im/deploy` folder, you must be able to run:
|
|
|
|
```
|
|
nomad plan im.hcl
|
|
```
|
|
|
|
Check that the proposed diff corresponds to what you have in mind.
|
|
If it seems OK, just copy paste the `nomad job run ... im.hcl` command proposed as part of the output of the `nomad plan` command.
|
|
|
|
From now, it will take around ~2 minutes to deploy the new images.
|
|
You can follow the deployment from the Nomad UI.
|
|
Bear in mind that, once the deployment is done on Nomad, you may still need to wait some minutes that Traefik refreshes its configuration.
|
|
|
|
If everythings worked as intended, you can commit and push your deployment file.
|
|
|
|
If something went wrong, you must rollback your deployment.
|
|
|
|
1. First, find a working deployment with [nomad job history](https://www.nomadproject.io/docs/commands/job/history)
|
|
2. Revert to this deployment with [nomad job revert](https://www.nomadproject.io/docs/commands/job/revert)
|
|
|
|
Now, if the deployment failed, you should probably investigate what went wrong offline.
|
|
I built a test stack with docker-compose in `app/<service>/integration` that should help you out (for now, test suites are only written for plume and jitsi).
