Before becreating release please download mongodb-4.0.23-src-bin.tgz from https://s4-viewer.cf.paas.bskyb.com/mongodb/mongodb-4.0.23-src-bin.tgz, remane it to mongodb-4.0.23.tgz and place it in to /src/mongod/ directory.

Below should be run only on brand new deployment.

To bootstrap replica set and create an admin user:

1. Pick a non-arbiter node after all nodes are deployed

2. Ssh into that node

3. Bootstrap replica set:

   export PATH=$PATH:/var/vcap/packages/mongod/ mongo /var/vcap/jobs/mongod/bootstrap/replica_set.js

4. Wait for a while for the replica set to initiate, the node on which bootstrap was done will become primary after few seconds

5. Create admin user:

   mongo /var/vcap/jobs/mongod/bootstrap/create_admin_user.js

Currently I cannot think of a way of automating this, hence these two scripts has to be run manually.

Automation is problematic because:

1. These two scripts should be run when all vms have been deployed. See (1)
2. Because we have a replica set name in the config, it is not possible to create admin user before replica set is bootstrapped.
