## Introduction
|
||||||
|
|
||||||
|
I am migrating several services from a k3s kubernetes cluster to a nixos server. Here is how I performed the operation with my [miniflux rss reader](https://miniflux.app/).
|
||||||
|
|
||||||
|
## Miniflux with nixos
|
||||||
|
|
||||||
|
Miniflux is packaged on nixos, but I am used to the container image so I am sticking with it for now.
|
||||||
|
|
||||||
|
Here is the module I wrote to deploy a miniflux container, configure postgresql and borg backups:
|
||||||
|
```nix
|
||||||
|
{ config, lib, pkgs, ... }:
|
||||||
|
{
|
||||||
|
imports = [
|
||||||
|
../../lib/borg-client.nix
|
||||||
|
../../lib/postgresql.nix
|
||||||
|
../../lib/nginx.nix
|
||||||
|
];
|
||||||
|
environment.etc."borg-miniflux-db.key" = {
|
||||||
|
mode = "0400";
|
||||||
|
source = ./borg-db.key;
|
||||||
|
};
|
||||||
|
services = {
|
||||||
|
borgbackup.jobs = let defaults = {
|
||||||
|
compression = "auto,zstd";
|
||||||
|
doInit = true;
|
||||||
|
encryption.mode = "none";
|
||||||
|
prune.keep = {
|
||||||
|
daily = 14;
|
||||||
|
weekly = 4;
|
||||||
|
monthly = 3;
|
||||||
|
};
|
||||||
|
startAt = "daily";
|
||||||
|
}; in {
|
||||||
|
"miniflux-db" = defaults // {
|
||||||
|
environment.BORG_RSH = "ssh -i /etc/borg-miniflux-db.key";
|
||||||
|
paths = "/tmp/miniflux.sql";
|
||||||
|
postHook = "rm -f /tmp/miniflux.sql";
|
||||||
|
preHook = ''rm -f /tmp/miniflux.sql; /run/current-system/sw/bin/pg_dump -h localhost -U miniflux -d miniflux > /tmp/miniflux.sql'';
|
||||||
|
repo = "ssh://borg@gcp.adyxax.org/srv/borg/miniflux-db";
|
||||||
|
};
|
||||||
|
};
|
||||||
|
nginx.virtualHosts."miniflux.adyxax.org" = {
|
||||||
|
forceSSL = true;
|
||||||
|
locations = {
|
||||||
|
"/" = {
|
||||||
|
proxyPass = "http://127.0.0.1:8084";
|
||||||
|
};
|
||||||
|
};
|
||||||
|
sslCertificate = "/etc/nginx/adyxax.org.crt";
|
||||||
|
sslCertificateKey = "/etc/nginx/adyxax.org.key";
|
||||||
|
};
|
||||||
|
postgresql = {
|
||||||
|
ensureUsers = [{
|
||||||
|
name = "miniflux";
|
||||||
|
ensurePermissions = { "DATABASE \"miniflux\"" = "ALL PRIVILEGES"; };
|
||||||
|
}];
|
||||||
|
ensureDatabases = ["miniflux"];
|
||||||
|
};
|
||||||
|
};
|
||||||
|
virtualisation.oci-containers.containers = {
|
||||||
|
miniflux = {
|
||||||
|
environment = {
|
||||||
|
ADMIN_PASSWORD = lib.removeSuffix "\n" (builtins.readFile ./admin-password.key);
|
||||||
|
ADMIN_USERNAME = "admin";
|
||||||
|
DATABASE_URL = "postgres://miniflux:" + (lib.removeSuffix "\n" (builtins.readFile ./database-password.key)) + "@10.88.0.1/miniflux?sslmode=disable";
|
||||||
|
RUN_MIGRATIONS = "1";
|
||||||
|
};
|
||||||
|
image = "miniflux/miniflux:2.0.50";
|
||||||
|
ports = ["127.0.0.1:8084:8080"];
|
||||||
|
};
|
||||||
|
};
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## Dependencies
|
||||||
|
|
||||||
|
The dependencies are mostly the same as in [my article about vaultwarden migration]({{< ref "migrating-vaultwarden.md" >}}#dependencies).
|
||||||
|
|
||||||
|
## Migration process
|
||||||
|
|
||||||
|
The first step is obviously to deploy this new configuration to the server, then I need to login and manually restore the backups.
|
||||||
|
```sh
|
||||||
|
make run host=dalinar.adyxax.org
|
||||||
|
```
|
||||||
|
|
||||||
|
The container will be failing because no password is set on the database user yet, so I stop it:
|
||||||
|
```sh
|
||||||
|
systemctl stop podman-miniflux
|
||||||
|
```
|
||||||
|
|
||||||
|
There is only one backup job for miniflux and it holds a dump of the database:
|
||||||
|
```sh
|
||||||
|
export BORG_RSH="ssh -i /etc/borg-miniflux-db.key"
|
||||||
|
borg list ssh://borg@gcp.adyxax.org/srv/borg/miniflux-db
|
||||||
|
borg extract ssh://borg@gcp.adyxax.org/srv/borg/miniflux-db::dalinar-miniflux-db-2023-11-20T00:00:01
|
||||||
|
psql -h localhost -U postgres -d miniflux
|
||||||
|
```
|
||||||
|
|
||||||
|
Restoring the data itself is done with the psql shell:
|
||||||
|
```sql
|
||||||
|
ALTER USER miniflux WITH PASSWORD 'XXXXXX';
|
||||||
|
\i tmp/miniflux.sql
|
||||||
|
```
|
||||||
|
|
||||||
|
Afterwards I clean up the database dump and restart miniflux:
|
||||||
|
```sh
|
||||||
|
rm -rf tmp/
|
||||||
|
systemctl start podman-miniflux
|
||||||
|
```
|
||||||
|
|
||||||
|
To wrap this up I migrate the DNS records to the new host, update my monitoring system and clean up the namespace on the k3s server.
|
||||||
|
|
||||||
|
## Conclusion
|
||||||
|
|
||||||
|
I did all this in november, I have quite the backlog of articles to write!
