Configuration reference

Enter these settings in the environment section of your private docker-compose.yaml. The Quick Start Compose example shows the complete file. The values below are examples, not defaults.

Settings

Setting	Purpose	Example value
BOLD_DOC_SERVER_LICENSE	Your BoldDocServer license key.	<your-license-key>
WOPI_HOST_URL	The BoldDocServer HTTPS address used by SharePoint and browsers.	https://bolddocserver.example.com
ENABLE_COLLABORATIVE_EDITING	Allow multiple users to edit the same document together. Requires Redis when enabled.	true
REDIS_CACHE_CONNECTION_STRING	Connection string for the Redis service used by collaboration.	<your-redis-connection-string>
AUTO_SAVE_INTERVAL_MS	Time between automatic saves, in milliseconds.	10000 (10 seconds)
VERSION_COMMIT_INTERVAL_MS	Time between version commits, in milliseconds.	300000 (5 minutes)
SPELLCHECK_DICTIONARY_PATH	Folder containing the Word spell-check dictionaries inside the container.	/app/data
SPELLCHECK_JSON_FILENAME	Spell-check dictionary filename.	spellcheck.json
SPELLCHECK_CACHE_COUNT	Spell-check cache count.	2
SSL_CERT_PATH	Certificate-chain file inside the container.	/https/certificate.crt
SSL_KEY_PATH	Certificate private-key file inside the container.	/https/private-key.key

Keep the configured file private and out of source control once it contains your license key or credentials. Managed deployments can supply these values through a secret store.

Public URL and WOPI

Set WOPI_HOST_URL to the HTTPS address users and SharePoint use to reach BoldDocServer:

WOPI_HOST_URL: "https://bolddocserver.example.com"

For a reverse proxy, use the proxy’s public address. Include the port if it is not 443. This setting is the BoldDocServer address; SharePoint supplies a separate document-specific URL called WOPISrc when opening a file.

Certificate and dictionary paths

The paths in the table are inside the container. The Quick Start mounts these host folders:

Host folder	Container folder	Contents
./certs	/https	Certificate chain and private key.
./data	/app/data	Spell-check dictionary package.

Keep the files in these host folders when replacing or updating a container. Documents are stored in SharePoint. For proxy certificate setup, see Deploy BoldDocServer.

Apply changes

After editing docker-compose.yaml, run these commands from its folder:

docker compose up -d
docker compose ps

Check that app is running. Open a document and try the feature you changed. If the service fails to start, see Container fails to start.
