## Running Docker Image
sudo docker run -i -t -d -p 80:80 onlyoffice/communityserver
This command will install ONLYOFFICE Community Server and all the dependencies it needs.
## Configuring Docker Image
### Running ONLYOFFICE Community Server on Different Port
To change the port, use the -p command. E.g.: to make your portal accessible via port 8080 execute the following command:
sudo docker run -i -t -d -p 8080:80 onlyoffice/communityserver
### Running ONLYOFFICE Community Server using HTTPS
Access to the onlyoffice application can be secured using SSL so as to prevent unauthorized access. While a CA certified SSL certificate allows for verification of trust via the CA, a self signed certificates can also provide an equal level of trust verification as long as each client takes some additional steps to verify the identity of your website. Below the instructions on achieving this are provided.
To secure the application via SSL basically two things are needed:
- **Private key (.key)**
- **SSL certificate (.crt)**
So you need to create and install the following files:
/opt/onlyoffice/Data/certs/onlyoffice.key
/opt/onlyoffice/Data/certs/onlyoffice.crt
When using CA certified certificates, these files are provided to you by the CA. When using self-signed certificates you need to generate these files yourself. Skip the following section if you are have CA certified SSL certificates.
#### Generation of Self Signed Certificates
Generation of self-signed SSL certificates involves a simple 3 step procedure.
**STEP 1**: Create the server private key
```bash
openssl genrsa -out onlyoffice.key 2048
```
**STEP 2**: Create the certificate signing request (CSR)
You have now generated an SSL certificate that's valid for 365 days.
#### Strengthening the server security
This section provides you with instructions to [strengthen your server security](https://raymii.org/s/tutorials/Strong_SSL_Security_On_nginx.html).
To achieve this you need to generate stronger DHE parameters.
```bash
openssl dhparam -out dhparam.pem 2048
```
#### Installation of the SSL Certificates
Out of the four files generated above, you need to install the `onlyoffice.key`, `onlyoffice.crt` and `dhparam.pem` files at the onlyoffice server. The CSR file is not needed, but do make sure you safely backup the file (in case you ever need it again).
The default path that the onlyoffice application is configured to look for the SSL certificates is at `/var/www/onlyoffice/Data/certs`, this can however be changed using the `SSL_KEY_PATH`, `SSL_CERTIFICATE_PATH` and `SSL_DHPARAM_PATH` configuration options.
The `/var/www/onlyoffice/Data/` path is the path of the data store, which means that you have to create a folder named certs inside `/opt/onlyoffice/Data/` and copy the files into it and as a measure of security you will update the permission on the `onlyoffice.key` file to only be readable by the owner.
You are now just one step away from having our application secured.
#### Available Configuration Parameters
*Please refer the docker run command options for the `--env-file` flag where you can specify all required environment variables in a single file. This will save you from writing a potentially long docker run command.*
Below is the complete list of parameters that can be set using environment variables.
- **ONLYOFFICE_HTTPS_HSTS_ENABLED**: Advanced configuration option for turning off the HSTS configuration. Applicable only when SSL is in use. Defaults to `true`.
- **ONLYOFFICE_HTTPS_HSTS_MAXAGE**: Advanced configuration option for setting the HSTS max-age in the onlyoffice nginx vHost configuration. Applicable only when SSL is in use. Defaults to `31536000`.
- **SSL_CERTIFICATE_PATH**: The path to the SSL certificate to use. Defaults to `/var/www/onlyoffice/Data/certs/onlyoffice.crt`.
- **SSL_KEY_PATH**: The path to the SSL certificate's private key. Defaults to `/var/www/onlyoffice/Data/certs/onlyoffice.key`.
- **SSL_DHPARAM_PATH**: The path to the Diffie-Hellman parameter. Defaults to `/var/www/onlyoffice/Data/certs/dhparam.pem`.
- **SSL_VERIFY_CLIENT**: Enable verification of client certificates using the `CA_CERTIFICATES_PATH` file. Defaults to `false`
## Installing ONLYOFFICE Community Server integrated with Document and Mail Servers
ONLYOFFICE Community Server is a part of ONLYOFFICE Free Edition that comprises also Document Server and Mail Server. To install them, follow these easy steps:
Alternatively, you can use [docker-compose](https://docs.docker.com/compose/install "docker-compose") to install the whole ONLYOFFICE Free Edition at once. For the mail server correct work you need to specify its hostname 'yourdomain.com'. Assuming you have docker-compose installed, execute the following command:
