## Getting help
Most Nextcloud Server administrative matters are covered in the official [Nextcloud Admin Manual](https://docs.nextcloud.com/server/latest/admin_manual/) or [other official Nextcloud documentation](https://docs.nextcloud.com) (which are all routinely updated).
**If you have any problems or usage questions while using the image, please ask for assistance on the [Nextcloud Community Help Forum](https://help.nextcloud.com)** rather than reporting them as "bugs" (unless they are bugs of course). This helps the
maintainers (who are volunteers) remain focused on making the image better (rather than responding solely to one-on-one support issues). (Tip: Some of the maintainers are also regular responders to help requests
on the [community help forum](https://help.nextcloud.com/).)
For the image specifically, we provide [some simple deployment examples](https://github.com/nextcloud/docker/?tab=readme-ov-file#running-this-image-with-docker-compose) as well as some more extensive [deployment examples](https://github.com/nextcloud/docker/tree/master/.examples). In addition, the [community help forum](https://help.nextcloud.com/) has a "how-to" section with further examples of other peoples' container based Nextcloud stacks.
Below you'll find the main documentation for using this image.
## Using the apache image
The apache image contains a webserver and exposes port 80. To start the container type:
Now you can access Nextcloud at http://localhost:8080/ from your host system.
WARNING: This example is only suitable for limited testing purposes. Please read on to understand how the image handles storing your data and other aspects you need to consider to establish a full Nextcloud stack.
## Using the fpm image
To use the fpm image, you need an additional web server, such as [nginx](https://docs.nextcloud.com/server/latest/admin_manual/installation/nginx.html), that can proxy http-request to the fpm-port of the container. For fpm connection this container exposes port 9000. In most cases, you might want to use another container or your host as proxy. If you use your host you can address your Nextcloud container directly on port 9000. If you use another container, make sure that you add them to the same docker network (via `docker run --network <NAME> ...` or a `docker compose` file). In both cases you don't want to map the fpm port to your host.
@ -47,7 +61,7 @@ $ docker run -d nextcloud:fpm
As the fastCGI-Process is not capable of serving static files (style sheets, images, ...), the webserver needs access to these files. This can be achieved with the `volumes-from` option. You can find more information in the [docker compose section](#running-this-image-with-docker-compose).
## Using an external database
By default, this container uses SQLite for data storage but the Nextcloud setup wizard (appears on first run) allows connecting to an existing MySQL/MariaDB or PostgreSQL database. You can also link a database container, e. g. `--link my-mysql:mysql`, and then use `mysql` as the database host on setup. More info is in the docker compose section.

## Persistent data
The Nextcloud installation and all data beyond what lives in the database (file uploads, etc.) are stored in the [unnamed docker volume](https://docs.docker.com/engine/tutorials/dockervolumes/#adding-a-data-volume) volume `/var/www/html`. The docker daemon will store that data within the docker directory `/var/lib/docker/volumes/...`. That means your data is saved even if the container crashes, is stopped or deleted.

If you'd prefer to use bind mounts instead of named volumes, for instance, when working with different device or network mounts for user data files and configuration:
Here’s the same example using Docker's more detailed `--mount`. Note that with `-v` or `--volume`, the specified folders are created automatically if they don't exist. However, when using `--mount` for bind mounts, the directories must already exist on the host, or Docker will return an error.
The examples above use figurative directory `/path/on/host/to/folder/` for bind mounts. Please modify the paths by using either a relative or absolute path.
NOTE: Do not confuse the `apps` and `custom_apps` folders. These folders contain different sets of apps, and mixing them will result in a broken installation. The former contains "shipped" apps, which come with Nextcloud Server. The latter contains apps you install from the App Store.
### Custom volumes
If mounting additional volumes under `/var/www/html`, you should consider:
- Confirming that [upgrade.exclude](https://github.com/nextcloud/docker/blob/master/upgrade.exclude) contains the files and folders that should persist during installation and upgrades; or
- Mounting storage volumes to locations outside of `/var/www/html`.
You should note that data inside the main folder (`/var/www/html`) will be overridden/removed during installation and upgrades, unless listed in [upgrade.exclude](https://github.com/nextcloud/docker/blob/master/upgrade.exclude). The additional volumes officially supported are already in that list, but custom volumes will need to be added by you. We suggest mounting custom storage volumes outside of `/var/www/html` and if possible read-only so that making this adjustment is unnecessary. If you must do so, however, you may build a custom image with a modified `/upgrade.exclude` file that incorporates your custom volume(s).

## Auto configuration via environment variables
The Nextcloud image supports auto configuration via environment variables. You can preconfigure everything that is asked on the install page on first run. To enable auto configuration, set your database connection via the following environment variables. You must specify all of the environment variables for a given database or the database environment variables defaults to SQLITE. ONLY use one database type!
The Nextcloud image supports auto configuration of the Nextcloud Server installation via environment variables. You can preconfigure everything that would otherwise be prompted for by the Nextcloud Installation Wizard (as well as a few other key parameters relevant to initial installation).
### Database parameters
To enable auto configuration, define your database connection via the following environment variables. If you set any group of values (i.e. all of `MYSQL_DATABASE`, `MYSQL_USER`, `MYSQL_PASSWORD`, `MYSQL_HOST`), they will not be requested via the Installation Wizard on first run.

If you set any group of values (i.e. all of `MYSQL_DATABASE`, `MYSQL_USER`, `MYSQL_PASSWORD`, `MYSQL_HOST`), they will not be asked in the install page on first run. With a complete configuration by using all variables for your database type, you can additionally configure your Nextcloud instance by setting admin user and password (only works if you set both):
### Initial admin account
If you specify all the variables for your database type (above), you can also auto configure your initial admin user and password (only works if you set both):
- `NEXTCLOUD_ADMIN_USER` Name of the Nextcloud admin user.
- `NEXTCLOUD_ADMIN_PASSWORD` Password for the Nextcloud admin user.
If you want, you can set the data directory, otherwise default value will be used.
Specifying a complete database and admin credential config set at initial deployment will result in a fully automated installation (i.e. bypassing the web-based Nextcloud Installation Wizard).
Addition parameters may also be set at installation time and are described below.
### Custom Data directory (`datadirectory`)
If you don't want to use the default data directory (`datadirectory`) location, you can set a custom one:
- `NEXTCLOUD_DATA_DIR` (default: `/var/www/html/data`) Configures the data directory where nextcloud stores all files from the users.
### Trusted domains (`trusted_domains`)
One or more trusted domains can be set through environment variable, too. They will be added to the configuration after install.
- `NEXTCLOUD_TRUSTED_DOMAINS` (not set by default) Optional space-separated list of domains

If you want to use Redis you have to create a separate [Redis](https://hub.docker.com/_/redis/) container in your setup / in your docker compose file. To inform Nextcloud about the Redis container, pass in the following parameters:
### Redis Memory Caching
To use Redis for memory caching as well as PHP session storage, specify the following values and also add a [Redis](https://hub.docker.com/_/redis/) container to your stack. See the [examples](https://github.com/nextcloud/docker/tree/master/.examples) for further instructions.
- `REDIS_HOST` (not set by default) Name of Redis container
- `REDIS_HOST_PORT` (default: `6379`) Optional port for Redis, only use for external Redis servers that run on non-standard ports.
- `REDIS_HOST_USER` (not set by default) Optional username for Redis, only use for external Redis servers that require a user.
- `REDIS_HOST_PASSWORD` (not set by default) Redis password
The use of Redis is recommended to prevent file locking problems. See the examples for further instructions.

To use an external SMTP server, you have to provide the connection details. Note that if you configure these values via Docker, you should **not** use the Nexcloud Web UI to configure external SMTP server parameters.

### Object Storage (Primary Storage)
By default, Nextcloud stores all files in `/var/www/html/data/` (or whatever custom data directory you've configured). Nextcloud also allows the use of object storages (like OpenStack
Swift or any Amazon S3-compatible implementation) as *Primary Storage*. This semi-replaces the default storage of files in the data directory. Note: This data directory might still be
used for compatibility reasons and still needs to exist. Check the [Nextcloud documentation](https://docs.nextcloud.com/server/latest/admin_manual/configuration_files/primary_storage.html) for more information.
To use an external S3 compatible object store as primary storage, set the following variables:

To customize other PHP limits you can simply change the following variables:
### PHP Configuration
To customize PHP limits you can change the following variables:
- `PHP_MEMORY_LIMIT` (default `512M`) This sets the maximum amount of memory in bytes that a script is allowed to allocate. This is meant to help prevent poorly written scripts from eating up all available memory but it can prevent normal operation if set too tight.
- `PHP_UPLOAD_LIMIT` (default `512M`) This sets the upload limit (`post_max_size` and `upload_max_filesize`) for big files. Note that you may have to change other limits depending on your client, webserver or operating system. Check the [Nextcloud documentation](https://docs.nextcloud.com/server/latest/admin_manual/configuration_files/big_file_upload_configuration.html) for more information.
- `PHP_OPCACHE_MEMORY_CONSUMPTION` (default `128`) This sets the `opcache.memory_consumption` value. It's the size of the shared memory storage used by OPcache, in megabytes.
To customize Apache max file upload limit you can change the following variable:
### Apache Configuration
To customize the Apache max file upload limit you can change the following variable:
- `APACHE_BODY_LIMIT` (default `1073741824` [1GiB]) This restricts the total

size of the HTTP request body sent from the client. It specifies the number of _bytes_ that are allowed in a request body. A value of **0** means **unlimited**.
### Auto configuration and Nextcloud updates
The image comes with special config files for Nextcloud that set parameters specific to containerized usage (e.g. `upgrade-disable-web.config.php`) or enable auto configuration via environment variables (e.g. `reverse-proxy.config.php`). Within the image, the latest version of these config files are located in `/usr/src/nextcloud/config`.
Check the [Nextcloud documentation](https://docs.nextcloud.com/server/latest/admin_manual/configuration_files/big_file_upload_configuration.html#apache) for more information.
During a fresh Nextcloud installation, the latest version (from the image) of these files are copied into `/var/www/html/config` so that they are stored within your container's persistent volume and picked up by Nextcloud alongside your local configuration.
### Using the image behind a reverse proxy and specifying the server host and protocol
By default, the apache image will replace the remote addr (IP address visible to Nextcloud) with the IP address from `X-Real-IP` if the request is coming from a reverse proxy in `10.0.0.0/8`, `172.16.0.0/12` or `192.168.0.0/16`. If you want Nextcloud to pick up the server host (`HTTP_X_FORWARDED_HOST`), protocol (`HTTP_X_FORWARDED_PROTO`) and client IP (`HTTP_X_FORWARDED_FOR`) from a trusted proxy, then disable rewrite IP and add the reverse proxy's IP address to `TRUSTED_PROXIES`.
- `APACHE_DISABLE_REWRITE_IP` (not set by default): Set to 1 to disable rewrite IP.
- `TRUSTED_PROXIES` (empty by default): A space-separated list of trusted proxies. CIDR notation is supported for IPv4.
If the `TRUSTED_PROXIES` approach does not work for you, try using fixed values for overwrite parameters.
- `OVERWRITEHOST` (empty by default): Set the hostname of the proxy. Can also specify a port.
- `OVERWRITEPROTOCOL` (empty by default): Set the protocol of the proxy, http or https.
- `OVERWRITECLIURL` (empty by default): Set the cli url of the proxy (e.g. https://mydnsname.example.com)
- `OVERWRITEWEBROOT` (empty by default): Set the absolute path of the proxy.
- `OVERWRITECONDADDR` (empty by default): Regex to overwrite the values dependent on the remote address.
- `FORWARDED_FOR_HEADERS` (empty by default): HTTP headers with the original client IP address
Check the [Nexcloud documentation](https://docs.nextcloud.com/server/latest/admin_manual/configuration_server/reverse_proxy_configuration.html) for more details.
Keep in mind that once set at install time, removing these environment variables later won't remove them from your `config/config.php`, due to how Nextcloud generates and merges the initial configuration at installation time. They can still, however, be removed manually from your `config/config.php`.
### Handling `Warning: /var/www/html/config/$cfgFile differs from the latest version of this image at /usr/src/nextcloud/config/$cfgFile` (aka: Auto configuration and Nextcloud updates)
The image comes with special config files for Nextcloud that set parameters specific to containerized usage (e.g. `upgrade-disable-web.config.php`) or enable auto configuration via environment variables (e.g. `reverse-proxy.config.php`). Not keeping these files up-to-date when this warning appears may cause certain auto configuration environment variables to be ignored or the image to not work as documented or expected.
During a fresh Nextcloud installation, the latest version (from the image) of these files are copied into `/var/www/html/config` so that they are stored within your container's persistent storage and picked up by Nextcloud alongside your local configuration.
The copied files, however, are **not** automatically overwritten whenever you update your environment with a newer Nextcloud image. This is to prevent local changes in `/var/www/html/config` from being unexpectedly overwritten. This may lead to your image-specific configuration files becoming outdated and image functionality not matching that which is documented.
Within each image, the latest version of these config files are located in `/usr/src/nextcloud/config`.
A warning will be generated in the container log output when outdated image-specific configuration files are detected at startup in a running container. When you see this warning, you should manually compare (or copy) the files from `/usr/src/nextcloud/config` to `/var/www/html/config`.
As long as you have not modified any of the provided config files in `/var/www/html/config` (other than `config.php`) or only added new ones with names that do not conflict with the image specific ones, copying the new ones into place should be safe (but check the source path `/usr/src/nextcloud/config` for any newly named config files to avoid new overlaps just in case).
Not keeping these files up-to-date when this warning appears may cause certain auto configuration environment variables to be ignored or the image to not work as documented or expected.

## Base version - FPM
When using the FPM image, you need another container that acts as web server on port 80 and proxies the requests to the Nextcloud container. In this example a simple nginx container is combined with the Nextcloud-fpm image and a MariaDB database container. The data is stored in docker volumes. The nginx container also needs access to static files from your Nextcloud installation. It gets access to all the volumes mounted to Nextcloud via the `volumes` option. The configuration for nginx is stored in the configuration file `nginx.conf`, that is mounted into the container. An example can be found in the examples section [here](https://github.com/nextcloud/docker/tree/master/.examples).
This setup provides **no TLS encryption** and is intended to run behind a proxy.

**If you have any problems or usage questions while using the image, please ask for assistance on the [Nextcloud Community Help Forum](https://help.nextcloud.com)** rather than reporting them as "bugs" (unless they really are bugs of course). This helps the
maintainers (who are volunteers) remain focused on making the image better (rather than responding solely to one-on-one support issues). (Tip: Some of the maintainers are also regular responders to help requests
on the [Nextcloud Community Help Forum](https://help.nextcloud.com).)
Most Nextcloud Server matters are covered in the official [Nextcloud Admin Manual](https://docs.nextcloud.com/server/latest/admin_manual/) or the [other official Nextcloud documentation](https://docs.nextcloud.com) (which are routinely updated).
