What runs op the director (pcf 1.11):

Resources#

Setting up your local BOSH environment#

First create your local BOSH director: 

bosh create-env ~/workspace/bosh-deployment/bosh.yml  \
 --state ./state.json \
 -o ~/workspace/bosh-deployment/virtualbox/cpi.yml \
 -o outbound-network.yml \
 -o ~/workspace/bosh-deployment/bosh-lite.yml \
 -o ~/workspace/bosh-deployment/bosh-lite-runc.yml \
 -o ~/workspace/bosh-deployment/jumpbox-user.yml \
 -o ~/workspace/bosh-deployment/uaa.yml \
 -o ~/workspace/bosh-deployment/credhub.yml \
 --vars-store ./creds.yml \
 -v director_name="Bosh Lite Director"  \
 -v internal_ip=192.168.50.6 \
 -v internal_gw=192.168.50.1 \
 -v internal_cidr=192.168.50.0/24 \
 -v outbound_network_name=NatNetwork
 
bosh alias-env vbox -e 192.168.50.6 --ca-cert <(bosh int ./creds.yml --path /director_ssl/ca)
 
export BOSH_ENVIRONMENT=vbox
export BOSH_CLIENT=admin
export BOSH_CLIENT_SECRET=`bosh int ./creds.yml --path /admin_password`

echo "updating cloud config..."
bosh -n update-cloud-config ~/workspace/bosh-deployment/warden/cloud-config.yml

Mind the uaa.yml and credhub.yml operator files.
When the deployment finishes you will have a creds.yml file that has all k

When you have this up and running, credhub should be running on port 8844 and use the local UAA (on port 8443) as it's authenticator.

Login to credhub#

First you need the credhub and uaa cli's, see the resources section for the download URLs. To install uaac, run sudo gem install cf-uaac.

Then you set the API to credhub: 

metskem@athena-2 ~/workspace/boshlite/deployments/vbox $ credhub api -s https://192.168.50.6:8844 --ca-cert <(bosh int creds.yml --path /credhub_tls/ca) --skip-tls-validation
Setting the target url: https://192.168.50.6:8844
Warning: The targeted TLS certificate has not been verified for this connection.
Warning: The --skip-tls-validation flag is deprecated. Please use --ca-cert instead.

First some jq magic to get the UAA URL from the credhub /info api: 

curl -k --silent https://192.168.50.6:8844/info|jq '.["auth-server"].url'

Login to credhub should be done with a UAA user, so login with that first (it took me quite some time to find out which user/password to use for uaa admin): 

uaac token client get uaa_admin -s $(cat <(bosh int creds.yml --path /uaa_admin_client_secret))
After that you are able to list the contexts and you can see you have scime.write (needed for adding users) and more: 
metskem@athena ~/workspace/boshlite/deployments/vbox uaac contexts

You need the second context (uaa_admin), as you can see it has all the scopes you need (clients.read password.write clients.secret clients.write uaa.admin scim.write scim.read).
Now you can also list the current uaa clients:

Create the uaa user that we will use to manage credhub: 

uaac user add credhub_user --emails harry.metske@gmail.com
# assign the password "credhub_user_pwd"

We have to create the credhub.write and credhub.read groups first and then make the newly created user a member of that: 

metskem@athena ~/workspace/boshlite/deployments/vbox uaac group add credhub.read

success
 metskem@athena ~/workspace/boshlite/deployments/vbox uaac member add credhub.write credhub_user
success
 metskem@athena ~/workspace/boshlite/deployments/vbox

You can get a token using the credhub-admin user (using the password from creds.yml:credhub_admin_client_secret: 

metskem@athena-2 ~/workspace/boshlite/deployments/vbox uaac token client get credhub-admin -s $(bosh int creds.yml --path /credhub_admin_client_secret)

Successfully fetched token via client credentials grant.
Target: https://192.168.50.6:8443
Context: credhub-admin, from client credhub-admin

And we can use the credhub client to login: 

metskem@athena-2 ~/workspace/boshlite/deployments/vbox credhub login -s https://192.168.50.6:8844 --ca-cert <(bosh int creds.yml --path /credhub_tls/ca) --skip-tls-validation --client-name credhub-admin --client-secret $(bosh int creds.yml --path /credhub_admin_client_secret)
Warning: The targeted TLS certificate has not been verified for this connection.
Warning: The --skip-tls-validation flag is deprecated. Please use --ca-cert instead.
Setting the target url: https://192.168.50.6:8844
Login Successful

Then generate an ssh key in credhub: 

metskem@athena-2 ~/workspace/boshlite/deployments/vbox credhub generate --type ssh --name /static/ssh_key
id: 7fb0017a-8b70-45a4-bfd5-8407d845ed73
name: /static/ssh_key
type: ssh
value: <redacted>
version_created_at: "2018-09-07T06:52:34Z"

And get it back from credhub by name : 

metskem@athena-2 ~/workspace/boshlite/deployments/vbox credhub get -n /static/ssh_key
id: 7fb0017a-8b70-45a4-bfd5-8407d845ed73

Finding creds#

Simply use the credhub find with no arguments: 

 metskem@athena-2 ~/workspace/boshlite/deployments/vbox credhub find
credentials:
- name: /yy/sample-rsa
  version_created_at: "2018-09-21T12:35:39Z"

Exporting (backup) creds#

Simply use the credhub export command.
