Proactively expire peers' login per account (#698)
Goals:

Enable peer login expiration when adding new peer
Expire peer's login when the time comes
The account manager triggers peer expiration routine in future if the
following conditions are true:

peer expiration is enabled for the account
there is at least one peer that has expiration enabled and is connected
The time of the next expiration check is based on the nearest peer expiration.
Account manager finds a peer with the oldest last login (auth) timestamp and
calculates the time when it has to run the routine as a sum of the configured
peer login expiration duration and the peer's last login time.

When triggered, the expiration routine checks whether there are expired peers.
The management server closes the update channel of these peers and updates
network map of other peers to exclude expired peers so that the expired peers
are not able to connect anywhere.

The account manager can reschedule or cancel peer expiration in the following cases:

when admin changes account setting (peer expiration enable/disable)
when admin updates the expiration duration of the account
when admin updates peer expiration (enable/disable)
when peer connects (Sync)
P.S. The network map calculation was updated to exclude peers that have login expired.

netbird Management Server

netbird management server will control and synchronize peers configuration within your Netbird account and network.

Command Options

The CLI accepts the command management with the following options:

start Netbird Management Server

Usage:
  netbird-mgmt management [flags]

Flags:
      --cert-file string            Location of your SSL certificate. Can be used when you have an existing certificate and don't want a new certificate be generated automatically. If letsencrypt-domain is specified this property has no effect
      --cert-key string             Location of your SSL certificate private key. Can be used when you have an existing certificate and don't want a new certificate be generated automatically. If letsencrypt-domain is specified this property has no effect
      --datadir string              server data directory location
  -h, --help                        help for management
      --letsencrypt-domain string   a domain to issue Let's Encrypt certificate for. Enables TLS using Let's Encrypt. Will fetch and renew certificate, and run the server with TLS
      --port int                    server port to listen on (default 33073)

Global Flags:
      --config string      Netbird config file location to write new config to (default "/etc/netbird")
      --log-file string    sets Netbird log path. If console is specified the the log will be output to stdout (default "/var/log/netbird/management.log")
      --log-level string    (default "info")

Run Management service (Docker)

You can run service in 2 modes - with TLS or without (not recommended).

Run with TLS (Let's Encrypt).

By specifying the --letsencrypt-domain the daemon will handle SSL certificate request and configuration.

In the following example 33073 is the management service default port, and 443 will be used as port for Let's Encrypt challenge and HTTP API.

The server where you are running a container has to have a public IP (for Let's Encrypt certificate challenge).

Replace with your server's public domain (e.g. mydomain.com or subdomain sub.mydomain.com).

# create a volume
docker volume create netbird-mgmt
# run the docker container
docker run -d --name netbird-management \
-p 33073:33073  \
-p 443:443  \
-v netbird-mgmt:/var/lib/netbird  \
-v ./config.json:/etc/netbird/config.json  \
netbirdio/management:latest \
--letsencrypt-domain <YOUR-DOMAIN>

An example of config.json can be found here management.json

Trigger Let's encrypt certificate generation:

curl https://<YOUR-DOMAIN>

The certificate will be persisted in the datadir/letsencrypt/ folder (e.g. /var/lib/netbird/letsencrypt/) inside the container.

Make sure that the datadir is mapped to some folder on a host machine. In case you used the volume command, you can run the following to retrieve the Mountpoint:

docker volume inspect netbird-mgmt
[
    {
        "CreatedAt": "2021-07-25T20:45:28Z",
        "Driver": "local",
        "Labels": {},
        "Mountpoint": "/var/lib/docker/volumes/mgmt/_data",
        "Name": "netbird-mgmt",
        "Options": {},
        "Scope": "local"
    }
]

Consequent restarts of the container will pick up previously generated certificate so there is no need to trigger certificate generation with the curl command on every restart.

Run without TLS.

# create a volume
docker volume create netbird-mgmt
# run the docker container
docker run -d --name netbird-management \
-p 33073:33073  \
-v netbird-mgmt:/var/lib/netbird  \
-v ./config.json:/etc/netbird/config.json  \
netbirdio/management:latest

Debug tag

We also publish a docker image with the debug tag which has the log-level set to default, plus it uses the gcr.io/distroless/base:debug image that can be used with docker exec in order to run some commands in the Management container.

shell $ docker run -d --name netbird-management-debug \
-p 33073:33073  \
-v netbird-mgmt:/var/lib/netbird  \
-v ./config.json:/etc/netbird/config.json  \
netbirdio/management:debug-latest

shell $ docker exec -ti netbird-management-debug /bin/sh
container-shell $
