Docker Compose
This is the documentation for how to use Docker Compose to set up Cobrowse Enterprise on a single host.
Dependencies
You'll need these installed on the host system before continuing:
​Docker​
​Docker Compose​
​NodeJS – version 10 or above
System Requirements
A single VM is all that is required to run Cobrowse. We recommend at least 2 vCPUs, 4GB memory, and 50GB SSD storage. This setup is a fast way to get started, and works well for many customers. For more information about system requirements, please see Sizing guidelines.
Cobrowse.io is deployed as containers, and we support many additional configurations to provide highly-available and large scale deployments. Please reach out below to discuss your specific requirements!
Initial Setup
Before you're ready to run Cobrowse you'll need to configure the host system with our managed Docker Compose file. The Docker Compose files defines the services and internal configuration that is required to easily set up the different Cobrowse server components.
Setup access to our private Docker registry. This is where your Docker host can obtain the Cobrowse Enterprise images. You will need the Cobrowse Enterprise repo password that has been assigned to you.
1
> docker login ghcr.io --username cobrowse-enterprise
Copied!
Enter your Cobrowse Enterprise repo password when prompted for a password.
Generate the Config Directory
We have provided a small command line utility to help you get started. This utility will gather the required config for your deployment. Run the following command from your terminal:
1
> npx cobrowse-enterprise create compose ./example
Copied!
You can replace "./example" with the directory where you wish to save the configuration data. The directory will be created if it does not exist yet.
Customize the Configuration
The installer above will generate a .env file that contains your configuration. You may edit this file to add further configuration. We support the following environment variables:
ENV VAR
Description
Example
Required
DOMAIN
Domain name to run Cobrowse on
mydomain.com
Yes
LICENSE
The license string you have been given by us
​
Yes
SSL_PORT
Port to accept HTTPS connections on
443
No
SSL_GENERATION
"automatic" (uses LetsEncrypt) or "manual"
automatic
No
SSL_VALIDATION
0 = disable cert validation (self signed certs)
0
No
SUPERUSERS
RegEx to specify super user email addresses
.*@example.com
No
Configuring DNS
In order to be able to access Cobrowse, you'll need to set up DNS records to point to your docker host. The process will depend on which domain provider you are using. See their relevant documentation for how to set this up.
Configuring SSL
Our Docker images will automatically create an SSL certificate for you using Let's Encrypt. In order for this process to work, your Docker host must be exposed to the internet and available on port 80 at the DOMAIN configured above. This is required in order for the domain validation to succeed before an SSL certificate is issued.
The certificates and configuration generated by Let's Encrypt will be available at ./data/certs relative to the path of the docker-compose.yml file.
SSL Configuration without Internet
If your environment does not have access to the internet, set SSL_GENERATION=manual in your environment configuration. You will then have to place the following files:
./data/certs/fullchain.pem – This is the certificate chain you wish to use
./data/certs/privkey.pem – This is the private key for your certificate
The files are relative to the placement of the docker-compose.yml file.
Starting Cobrowse
You're now ready to try starting Cobrowse. Just run these commands in the same location as the docker-compose.yml file:
1
> docker-compose up
Copied!
When all the docker containers have started, Cobrowse should be available on the domain you configured above. Tip: add --detach to run the services in the background.
Open up a web browser and navigate to your Cobrowse domain, you should then be able to use the email registration flow to create a new account and test out your deployment!
Running your instance
​
Shutting down Cobrowse
Open up a terminal to the location of the docker-compose.yml file and run:
1
> docker-compose down
Copied!
Other considerations
Managing the database
The Cobrowse docker-compose file will start a MongoDB instance for you. The database storage will be exposed on a docker volume at ./data/db relative to the path of the docker-compose.yml file.
Backing up MongoDB
You are responsible for backing up the database regularly. Cobrowse will not do this automatically in any way. See the MonogDB docs for recommendations on backup strategies.
Upgrading Cobrowse
The config directory created by our command line utility is a git repo. You can update to the latest version by doing:
1
> docker-compose down
2
> git pull upstream master
3
> docker-compose up
Copied!
Note: We recommend making a database backup before upgrading to new versions
Host firewalls
If you're running additional firewalls to those that Docker sets up automatically, you need to ensure that port 80 (HTTP) and port 443 (HTTPS) are both exposed for the docker host.
