How to use this image

$ docker run --link some_mongo_container:mongo -p 8081:8081 -e ME_CONFIG_MONGODB_URL="mongodb://mongo:27017" mongo-express

Then you can hit http://localhost:8081 or http://host-ip:8081 in your browser.

Security Notice

JSON documents are parsed through a javascript virtual machine, so the web interface can be used to execute malicious javascript on a server.

mongo-express should only be used privately for development purposes.

Configuration

Environment vairables are passed to the run command for configuring a mongo-express container.

Name                            | Default         | Description
--------------------------------|-----------------|------------
ME_CONFIG_MONGODB_URL        	| 'mongodb://mongo:27017' | MongoDB connection string
ME_CONFIG_BASICAUTH_USERNAME    | ''              | mongo-express web username
ME_CONFIG_BASICAUTH_PASSWORD    | ''              | mongo-express web password
ME_CONFIG_MONGODB_ENABLE_ADMIN  | 'true'          | Enable admin access to all databases. Send strings: `"true"` or `"false"`
ME_CONFIG_OPTIONS_EDITORTHEME   | 'default'       | mongo-express editor color theme, [more here](http://codemirror.net/demo/theme.html)
ME_CONFIG_REQUEST_SIZE          | '100kb'         | Maximum payload size. CRUD operations above this size will fail in [body-parser](https://www.npmjs.com/package/body-parser).
ME_CONFIG_SITE_BASEURL          | '/'             | Set the baseUrl to ease mounting at a subdirectory. Remember to include a leading and trailing slash.
ME_CONFIG_SITE_COOKIESECRET     | 'cookiesecret'  | String used by [cookie-parser middleware](https://www.npmjs.com/package/cookie-parser) to sign cookies.
ME_CONFIG_SITE_SESSIONSECRET    | 'sessionsecret' | String used to sign the session ID cookie by [express-session middleware](https://www.npmjs.com/package/express-session).
ME_CONFIG_SITE_SSL_ENABLED      | 'false'         | Enable SSL.
ME_CONFIG_SITE_SSL_CRT_PATH     | ''              | SSL certificate file.
ME_CONFIG_SITE_SSL_KEY_PATH     | ''              | SSL key file.

The following are only needed if ME_CONFIG_MONGODB_ENABLE_ADMIN is "false"

Name                            | Default         | Description
--------------------------------|-----------------|------------
ME_CONFIG_MONGODB_AUTH_DATABASE | 'db'            | Database name
ME_CONFIG_MONGODB_AUTH_USERNAME | 'admin'         | Database username
ME_CONFIG_MONGODB_AUTH_PASSWORD | 'pass'          | Database password

Example

docker run -it --rm \
	--name mongo-express \
	--link web_db_1:mongo \
	-p 8081:8081 \
	-e ME_CONFIG_MONGODB_URL="mongodb://mongo:27017" \
	-e ME_CONFIG_OPTIONS_EDITORTHEME="ambiance" \
	-e ME_CONFIG_BASICAUTH_USERNAME="user" \
	-e ME_CONFIG_BASICAUTH_PASSWORD="fairly long password" \
	mongo-express

This example links to a container name typical of docker-compose, changes the editor's color theme, and enables basic authentication.
