Management / Unit (amd64, mysql) hit the 20 minute go test budget on #7516. The package was not hung: each of the 133 test store creations in management/server paid about 1.6s on MySQL for CREATE DATABASE, the pre-migrations, a 40-table AutoMigrate and the post-migrations, which puts the package at 10 minutes on a healthy runner and over the budget on a slow one. The migration now runs once per test binary into a template database and each test database is cloned from it, with CREATE DATABASE ... TEMPLATE on Postgres and a replay of SHOW CREATE TABLE on MySQL. The MySQL test container also drops the binary log, doublewrite buffer and per-commit redo fsync. Two goroutine leaks in the test helpers are fixed. tools/gotestsummary turns the go test -json stream into a readable log, and the Management unit and integration jobs now pipe through it, so a timeout names the tests still running. On MySQL, management/server went from 10m16s to 6m36s.
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 $
