The following sections describe how to get COSMOS installed on various operating systems. A major difference between COSMOS v4 and COSMOS v5 is the usage of containers. This document should help you setup you host machine to allow you to have a running version of COSMOS in no time.
Installing COSMOS on Host Machines
- Minimum Resources allocated to Docker: 8GB RAM, 1 CPU, 80GB Disk
- Recommended Resources allocated to Docker: 16GB RAM, 2+ CPUs, 100GB Disk
Note: As of December 2021 the COSMOS Docker containers are based on the Alpine Docker image.
Download the latest COSMOS 5 from the Github releases. You can also clone the master branch to get the latest updates.
Extract the archive somewhere on your host computer.
The COSMOS 5 containers are designed to work and be built in the presence of an SSL Decryption device. To support this a cacert.pem file can be placed at the base of the COSMOS 5 project that includes any certificates needed by your organization. Note: If you set the path to the ssl file in the
SSL_CERT_FILE environment variables the cosmos-control setup script will copy it and place it for the docker container to load.
Increasingly organizations are using some sort of SSL decryptor device which can cause curl and other command line tools like git to have SSL certificate problems. If installation fails with messages that involve "certificate", "SSL", "self-signed", or "secure" this is the problem. IT typically sets up browsers to work correctly but not command line applications. Note that the file extension might not be .pem, it could be .pem, crt, .ca-bundle, .cer, .p7b, .p7s, or potentially something else.
The workaround is to get a proper local certificate file from your IT department that can be used by tools like curl (for example mine is at C:\Shared\Ball.pem). Doesn't matter just somewhere with no spaces.
Then set the following environment variables to that path (ie. C:\Shared\Ball.pem)
Here are some directions on environment variables in Windows:
Windows Environment Variables
You will need to create new ones with the names above and set their value to the full path to the certificate file.
At Ball please contact email@example.com for assistance.
If you're building in a offline environment or want to use a private Rubygems, NPM or APK server (e.g. Nexus), you can update the following environment variables: RUBYGEMS_URL, NPM_URL, APK_URL, and more in the .env file. Example values:
Create a zip file which can be transferred by running
cosmos-control.bat util zip
If you're on Unix, once you unzip the file run the following:
find . -name "*.sh" | xargs chmod +x
cosmos-control.bat start (Windows), or
cosmos-control.sh start (linux/Mac).
If you see an error indicating docker daemon is not running ensure Docker and Docker compose is installed and running. If it errors please try to run
docker --version or
docker-compose --version and try to run the start command again. If the error continues please include the version in your issue if you choose to create one.
cosmos-control.* can help solve some of the short falls of docker-compose when building the containers.
cosmos-control.* takes multiple arguments. Run with no arguments for help. An example run of cosmos-control.bat with no arguments will show a usage guide.
.\cosmos-control.bat Usage: "cosmos-control.bat" [start, stop, cleanup, build, run, deploy, util] * build: build the containers for cosmos * start: run the docker containers for cosmos * stop: stop the running docker containers for cosmos * restart: stop and run the minimal docker containers for cosmos * cleanup: cleanup network and volumes for cosmos ...
Docker minio/mc issue
On some windows systems we have seen docker error when building the cosmosc2-minio-init container. It could be due to an issue downloading the minio mc container. To solve this you can manually pull the minio container. Open the minio-init Dockerfile, note the FROM line, e.g.
FROM minio/mc:RELEASE.2021-12-10T00-14-28Z, and manually pull the image.
Note: Image name may be different in current Dockerfile
docker pull minio/mc:RELEASE.2021-12-10T00-14-28Z
This should download the minio/mc container locally and not have docker-compose pull the image on build. Now re-run cosmos-control start and continue on the cosmos adventure.
COSMOS 5 will be built and when ready should be running (~15 mins for first run, ~2 for subsequent). Running
docker ps can help show the running containers.

Let us know what could be better!
Both using and hacking on COSMOS should be fun, simple, and easy, so if for some reason you find it's a pain, please create an issue on GitHub describing your experience so we can make it better.
