Move Docker Hub access requests out of your follow-up queue
A clear Slack DM asking for organization access can become a Docker Hub invitation, without leaving the request waiting in your inbox.
Trigger
Direct Message Received
Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.
Action
Add Organization Member
Tool to send an invitation for a user to join a Docker Hub organization. Use when you need to grant membership by inviting a user via their username after choosing the appropriate role.
Why this helps
Access requests often sit in DMs until a founder remembers to switch tools and send the invite.
- Reduces the mental load of tracking access requests.
- Acts on the request while its context is fresh.
- Keeps routine onboarding from becoming a separate admin task.
Setup
Build it in a few focused steps.
- 1Connect Slack and Docker Hub to Notis once in the portal.
- 2Create an automation with one instruction to invite the requester to the named Docker Hub organization when a DM clearly asks for access and provides the necessary username and role.
- 3Select Direct Message Received as the trigger and choose a channel for run reports.
- 4Test with a real access request from an account where an invitation is appropriate.
Questions about this workflow
Can it infer the Docker Hub username from any name?
Ask the prompt to proceed only when the message includes a reliable Docker Hub username and organization.
Can I limit which role is granted?
Yes. State the permitted role in the plain-language instruction and require the request to meet your criteria.
