Introduction to nc-env
nc-env is a project that enables you to provision isolated Nextcloud test environments in your machine. It is built on vagrant and LXD.
|⚡ This project is a personal initiative, without any official support by Nextcloud GmbH|
|⚡ The templates in this repository are designed and developed for testing and development environments, not for production|
You can leverage this project to:
- Quickly setup and run an isolated Nextcloud instance in your machine
- Try features or troubleshoot issues without any manual installation
- Learn and explore the integration of Nextcloud with common enterprise systems, such as LDAP, Single Sign On or an Office Editing Service
Setup the environment
Install and configure LXD
The initial configuration guide is here and applies to many Linux distributions.
If you are interested in understanding the difference between application and system containers, this is a good short article that explains it.
Configure the host to resolve container hostnames
While container hostnames can be defined in
/etc/hosts, you can avoid this additional manual step by defining a systemd service that instructs the resolver to query the built-in DNS service for domains ending with
To do that, follow these instructions (reference documentation here)
Get the network interface used by LXD (by default
lxdbr0, and assumed as such in the following) and the IP of the built-in DNS (in this output
$ lxc network list +--------+----------+---------+---------------+-------------------------+-------------+---------+ | NAME | TYPE | MANAGED | IPV4 | IPV6 | DESCRIPTION | USED BY | +--------+----------+---------+---------------+-------------------------+-------------+---------+ | lxdbr0 | bridge | YES | 10.23.46.1/24 | fd42:fa6c:5eee:12::1/64 | | 25 | +--------+----------+---------+---------------+-------------------------+-------------+---------+
Set the configuration variables
dns.domain (this is optional, the default is
$ lxc network set lxdbr0 dns.domain 'localenv.com' $ lxc network set lxdbr0 dns.mode managed
Create a systemd unit file called
lxd-dns-lxdbr0.service that allows this setup to be persistent across machine reboots.
$ sudo cat /etc/systemd/system/lxd-dns-lxdbr0.service [Unit] Description=LXD per-link DNS configuration for lxdbr0 BindsTo=sys-subsystem-net-devices-lxdbr0.device After=sys-subsystem-net-devices-lxdbr0.device [Service] Type=oneshot ExecStart=/usr/bin/resolvectl dns lxdbr0 10.23.46.1 ExecStart=/usr/bin/resolvectl domain lxdbr0 '~localenv.com' [Install] WantedBy=sys-subsystem-net-devices-lxdbr0.device
Enable it and start it:
$ sudo systemctl daemon-reload $ sudo systemctl enable lxd-dns-lxdbr0.service $ sudo systemctl start lxd-dns-lxdbr0.service $ sudo systemctl status lxd-dns-lxdbr0.service ? lxd-dns-lxdbr0.service - LXD per-link DNS configuration for lxdbr0 Loaded: loaded (/etc/systemd/system/lxd-dns-lxdbr0.service; enabled; vendor preset: enabled) Active: inactive (dead) since Tue 2022-01-04 12:32:09 CET; 1h 26min ago Process: 1916 ExecStart=/usr/bin/resolvectl dns lxdbr0 10.23.46.1 (code=exited, status=0/SUCCESS) Process: 1917 ExecStart=/usr/bin/resolvectl domain lxdbr0 ~localenv.com (code=exited, status=0/SUCCESS) Main PID: 1917 (code=exited, status=0/SUCCESS) CPU: 8ms ene 04 12:32:09 my-host systemd: Starting LXD per-link DNS configuration for lxdbr0... ene 04 12:32:09 my-host systemd: lxd-dns-lxdbr0.service: Deactivated successfully. ene 04 12:32:09 my-host systemd: Finished LXD per-link DNS configuration for lxdbr0. $ sudo resolvectl status lxdbr0 Link 4 (lxdbr0) Current Scopes: DNS Protocols: -DefaultRoute +LLMNR -mDNS -DNSOverTLS DNSSEC=no/unsupported Current DNS Server: 10.23.46.1 DNS Servers: 10.23.46.1 DNS Domain: ~localenv.com
Install and configure vagrant
You can learn about installation here. For Ubuntu-based systems, it is as simple as
sudo apt install vagrant
Install LXD plugin vagrant-lxd
This plugin adds the ability to manage containers with LXD. See here for installation instructions.
Download it here) and run
mkcert --install. This command installs a local certificate for the Certificate Authority along with its key. This is handy as it avoids many warnings and errors when
dealing with self-trusted certificates.

Provision a container
Once the environment is ready, an instance of the container template that you want to work with can be created and started.
Copy it in the target folder and make sure that the
artifacts folder contains all the artifacts documented in the
Readme.md file, located in the template root folder.
If some additional configuration step is needed, it will be also documented there.
After running the provisioning step, make sure your host system is able to resolve the domain name that you specified for the container, for example by adding an entry in
Afterwards, the environment is ready to be used.
