Components

The Components tab is where you define the technical details for each container that makes up your application.

In this tab, you define and manage each container (component) that makes up your application.

Click the "+" icon to add a new component
Use the "red x" icon to delete or reset an existing component
Each component is configured independently with its own image, ports, resources, and settings

Enter the Docker container repository

You need to enable "Enterprise" at the General Tab to use this feature

Define one or multiple shared data volumes for your container using the format:

/path

Data Path Mode

r: (Replicated After Readiness) Use r: to delay data synchronization until all container instances are fully running. This ensures volumes are only mounted and synced when all backends are confirmed live—ideal for consistency in replicated setups.
g: (Primary/Standby) Use g: to enable a primary/standby configuration. One instance acts as the primary (read–write), while the others stay in standby mode and only replicate changes from the primary.
No Prefix If no prefix (r: or g:) is used, the path is treated as a standard local volume. These are non-persistent and not synchronized between instances.

ℹ️ Extent "Detailed Information & Sync Behavior" for more detailed information.

Define environment variables for your container using the syntax: VARIABLE=value

Click the "Environment Variables" button
Enter a Key, and Value, then click the "+ icon" to save the entry.
You can add multiple ENV entries
You can import ENVs from JSON
- Format: JSON array of strings
- Example: ["KEY=value", "FOO=bar", "PORT=3000"]
⚠️ Environment variables are publicly accessible via the FluxCloud API if you have not enabled "Enterprise" in the General Tab.

Define CLI commands for your container in JSON array format Example: ["--logs", "--history", "version"]

Click the "Commands" button
Enter the command, then click the "+ icon" to save the entry.
You can add multiple run commands
You can import Commands from JSON
- Format: JSON array of strings
- Example: ["npm install", "npm run build", "node server.js"]
⚠️ Commands are publicly accessible via the FluxCloud API if you have not enabled "Enterprise" in the General Tab.

Set both the Exposed Port and the Docker Container Port

Exposed Port must be between 1024–65535
- Restricted ports (do not use): ['16100–16299', '26100–26299', '30000–30099', 22, 23, 25, 123, 161, 512, 513, 3388, 3889, 4444, 5800, 5900, 5901, 8384, 27017]
Docker Container Port should correspond to your app’s internal port (e.g., 80 for web servers)

Once a Port Forwarding rule is added, you can assign a custom domain
