# Cosmium
|
|
|
|
Cosmium is a lightweight Cosmos DB emulator designed to facilitate local development and testing. While it aims to provide developers with a solution for running a local database during development, it's important to note that it's not 100% compatible with Cosmos DB. However, it serves as a convenient tool for E2E or integration tests during the CI/CD pipeline. Read more about compatibility [here](./docs/COMPATIBILITY.md).
|
|
|
|
One of Cosmium's notable features is its ability to save and load state to a single JSON file. This feature makes it easy to load different test cases or share state with other developers, enhancing collaboration and efficiency in development workflows.
|
|
|
|
# Getting Started
|
|
|
|
### Installation via Homebrew
|
|
|
|
You can install Cosmium using Homebrew by adding the `pikami/brew` tap and then installing the package.

|
|
|
```sh
|
|
brew tap pikami/brew

This will download and install Cosmium on your system, making it easy to manage and update using Homebrew.
|
|
|
|

|
|
|

|
|
|
|
```sh
|
|
cosmium -Persist "./save.json"
|
|
```
|
|
|
|
Connection String Example:

AccountEndpoint=https://localhost:8081/;AccountKey=C2y6yDjf5/R+ob0N8A7Cgv30VRDJIWEHLM+4QDU5DE2nQ9nDuVTqobD4b8mGGyPMbIZnqyMsEcaGQy67XIw/Jw==;
|
|
```
|
|
|
|
### Running Cosmos DB Explorer
|
|
|
|
If you want to run Cosmos DB Explorer alongside Cosmium, you'll need to build it yourself and point the `-ExplorerDir` argument to the dist directory. Please refer to the [Cosmos DB Explorer repository](https://github.com/Azure/cosmos-explorer) for instructions on building the application.
|
|
|
|
Once running, the explorer can be reached by navigating following URL: `https://127.0.0.1:8081/_explorer/` (might be different depending on your configuration).
|
|
|
|
### Running with docker (optional)
|
|
|
|
If you wan to run the application using docker, configure it using environment variables see example:
|
|
|
|
```sh
|
|
docker run --rm \
|
|
-e COSMIUM_PERSIST=/save.json \
|
|
-v ./save.json:/save.json \
|
|
-p 8081:8081 \
|
|
ghcr.io/pikami/cosmium
|
|
```
|
|
|
|
### SSL Certificate
|
|
|
|
By default, Cosmium uses a pre-generated SSL certificate. You can provide your own certificates by specifying paths to the SSL certificate and key (PEM format) using the `-Cert` and `-CertKey` arguments, respectively.
|
|
|
|
To disable SSL and run Cosmium on HTTP instead, you can use the `-DisableTls` flag. However most applications will require HTTPS.
|
|
|
|
### Other Available Arguments
|
|
|
|
- **-AccountKey**: Account key for authentication (default "C2y6yDjf5/R+ob0N8A7Cgv30VRDJIWEHLM+4QDU5DE2nQ9nDuVTqobD4b8mGGyPMbIZnqyMsEcaGQy67XIw/Jw==")
|
|
- **-DisableAuth**: Disable authentication
|
|
- **-Host**: Hostname (default "localhost")
|
|
- **-InitialData**: Path to JSON containing initial state
|
|
- **-Persist**: Saves data to the given path on application exit (When `-InitialData` argument is not supplied, it will try to load data from path supplied in `-Persist`)
|
|
- **-Port**: Listen port (default 8081)
|
|
- **-Debug**: Runs application in debug mode, this provides additional logging
|
|
|
|
These arguments allow you to configure various aspects of Cosmium's behavior according to your requirements.
