Stacks in Celigo

The Stacks are simple server environments used to host code for hooks, wrappers, connector installers, and settings pages. Within stacks, for example, you can enable “hook” fields or expose custom code that you can configure when defining an export or import. Run operations on different servers in stacks

integrator.io is a distributed system in which different components can run on different servers to perform multiple operations efficiently. You store references to the other servers in the stack, and integrator.io can invoke resources on servers you reference in the stack during runtime. Hooks or wrappers are the integrator.io extensions that run on separate servers that integrator.io can call during runtime. The stack can be one server or a set of servers running behind a load balancer. Store the system token for the stack as an environment variable on the server where the extension code is running.

integrator.io supports execution of extension functions through the following extension types:

1. Express based app running on a server

2. AWS Lambda.

Note: Click Resources > Stacks see the list of all previously created stacks.

Create an AWS Lambda stack

Create a server stack

Create an AWS Lambda stack

Use the following steps to create a AWS Lambda stack:

1. Navigate to Resources > Stacks. You'll need to have the Developer Mode enabled to access Stacks.

2. Click + Create stack.

3. In the Name field, enter an appropriate name for the stack that you are about to create.

4. Use the drop-down menu in the Type field to select the AWS Lambda.

Create a server stack

Use the following steps to create an server stack:

1. Navigate to Resources > Stacks. You'll need to have Developer Mode to enable the access Stacks.

2. Click + Create stack.

3. In the Name field, enter an appropriate name for the stacks that you are about to create.

4. Use drop-down menu in the Type field to select Server.

5. Enter the server URL in the Host field.

6. Click Save & close.

Share stacks with other users

Use the following steps to share a stack:

1. First Click Resources > Stacks to see the list of all previously created stacks.

2. Click the Action overflow menu for the stack and select Share stack.

3. Click +Invite user.

4. Enter the email address of the integrator.io user you want to share the stack with.

The user you've shared a stack with receives a notification that the stack has been shared with them. Until they accept the shared stack with the link in the notification, the Status column value displays as Pending. Once the user accepts, this value changes to Accepted. Click Refresh to see the latest status of your invitation.

After the invited user accepts the shared stack, the stack is available from that user's flow pages.

Remove user access to a shared stack

Use the following steps to remove user access to a shared stack:

1. Click Resources > Stacks to see the list of all previously created stacks.

2. Click the Actions overflow (...) menu for the shared item and select Share stack.

3. You can use the Off/On toggle to temporarily remove a user’s access from a stack. To permanently remove access, click the trash icon in the Action column next to the user whose access to the stack you want to remove.

The share request is permanently deleted from the system, so you must send a new invitation to reshare the stack with that user. You can’t remove user access from a shared stack if the stack is currently in use by that user. In such cases, an error message displays and the share request will not be removed. You can only remove user access to a stack if the stack's reference has been removed from all connections, imports, and exports.
