This project demonstrates how you can use the Pulumi Automation SDK to provision resources that require connectivity through a bastion host, establish a connection through the bastion host, and then provision resources through the connection.
- You will need the Pulumi CLI installed.
- This particular project uses TypeScript so you will need Node.js installed. This same automation application could be implemented in any of other languages that Pulumi supports.
- For execution, and the SSH tunnel to work correctly, the current implementation requires that the ssh key is already established with
ssh-agent
. The code could be modified to take the ssh private key as an input.
The automation application requires the following three arguments:
- the operation to perform -
up
,refresh
, ordestroy
- the stack name
- the path to the ssh public key for connecting to the bastion host
e.g.
npm run pulumi \
up \
dev \
~/.ssh/key.pub
% npm run pulumi up dev ~/.ssh/key.pub
> pulumi-automation-sdk-ssh-tunnel@0.0.1 pulumi
> ./node_modules/ts-node/dist/bin.js pulumi.ts "up" "dev" "/Users/clstokes/.ssh/key.pub"
Running [up] on stack [dev]
