Verify you can pull from Repo1 and IronBank💣

Note: Platform One has 4 Useful Places to pull from

  1. Repo1’s Gitlab Git Repo: repo1.dso.mil Repo1’s Gitlab Git Repo is the Upstream Source of Truth Git Repo for P1’s IaC/CaC
  2. Repo1’s Gitlab Docker Registry: registry.dso.mil The Big Bang team sometimes stores docker images needed for tooling and prototyping here. Such docker images are stored here to signify that they have not gone through the official IronBank Process yet.
  3. IronBank’s Frontend GUI (where justifications and risk assessment are stored): ironbank.dso.mil
  4. IronBank’s Harbor Docker Registry: registry1.dso.mil Source of truth for IronBank Images.

Task #1 Clone the Engineering Cohort Repo from Repo1’s Gitlab Git Repo: repo1.dso.mil💣

Repo1’s Gitlab Git Repo is the Upstream Source of Truth Git Repo for P1’s IaC/CaC

cd ~/Desktop
git config --global user.name "FIRST_NAME LAST_NAME"
git config --global user.email "MY_NAME@workemail.com or .mil"
cat ~/.gitconfig  #or cat ~/.git/config
git clone https://repo1.dso.mil/platform-one/onboarding/big-bang/engineering-cohort.git

Task #2 Update your local clone of the Big Bang Residency git repo, by pulling the latest changes💣

Notes:
This path is based on assumption that you cloned to the location shown above.
 Also, git commands are sensitive to your current working directory

cd ~/Desktop/engineering-cohort
git pull origin master

Task #3 Pull an Image from Repo1 Gitlab’s Docker Registry💣

docker pull registry.dso.mil/platform-one/plugins/kustomize/all:v0.1.1

# Note for Ubuntu users, if you get the following error (rare edge case)
# Error response from daemon: Get "https://registry.dso.mil/v2/": dial tcp: lookup registry.dso.mil: Temporary failure in name resolution
# then try
sudo systemctl restart systemd-resolved.service

The above container image is publicly accessible (no auth needed).
If an image does require auth use a Gitlab Personal Access token for credentials.

Task #4 Visit the IronBank Frontend website💣

  1. In Chrome visit ironbank.dso.mil
  2. Click Browse all Hardened Containers
  3. Type argo
  4. Click Argocd
  5. Look at the interface & versions available

Task #5 Pull a Docker Image from IronBank💣

  1. Visit registry1.dso.mil
  2. Login via OIDC Provider
  3. Navigate to Project ironbank
  4. You’ll see a search magnifying glass, click it and you’ll have the option to filter repositories
  5. search “ubi” (Side Note: UBI stands for Red Hat Universal Base Image)
  6. Click ironbank/redhat/ubi/ubi8
  7. Click the Button in the Pull Command column that corresponds to the latest tag mentioned in the Tags Column.
  8. Make a mental note of the other tag that is present (at the time of writing I see 8.5)
  9. Paste that command into your terminal (initial error is expected and will be fixed in a subsequent step) 
    docker pull registry1.dso.mil/ironbank/redhat/ubi/ubi8:8.5
# Error response from daemon: unauthorized: unauthorized to access repository: ironbank/redhat/ubi/ubi8,
# action: pull: unauthorized to access repository: ironbank/redhat/ubi/ubi8, action: pull
  10. In the top right click your name, then go to User Profile
  11. Your User Profile section will have a CLI secret that you can copy

  12. Type Login Command into Bash, here’s an example

    Use the -u option for username (use your own) 

    docker login registry1.dso.mil -u cmcgrath
    The above command will prompt you for a password, that’s your CLI secret from step 12

  13. Retry the docker pull command in step 9 and it’ll now work.

  14. Run the below docker command using a tag reference instead of a SHA256 reference, note the latest tag at the time of writing was 8.5, during step 9 you may end up seeing a newer tag, if a newer tag like :8.6 exists, use that instead. 
    docker pull registry1.dso.mil/ironbank/redhat/ubi/ubi8:8.5

Task #6 Rotate your IronBank Docker Pull Credential💣

Note: IronBank (registry1.dso.mil) is an instance of Harbor. At one point it was mis-configured such that docker pull credentials were tied to the life of your OIDC login, and the IronBank docker pull credentials would stop working after 30 minutes, and refuse to pull images until you logged into the IronBank GUI which would refresh an OIDC token and cause the pull credentials to start working again until the token expired 30 mins later.

IronBank was reconfigured such that newly minted pull credentials are created with an offline flag that separates them from the OIDC life cycle/makes them work as expected. (where they keep working regardless of if you’d recently logged into the GUI or not.)

Rotate your Iron Bank Docker Pull Credentials: This ensures that you don’t have a docker pull credential that was created with the old misconfiguration that ties it into the OIDC token life cycle. The newly rotated credential will get generated using the new config / offline flag, such that it works as intended.

How to Rotate IB Docker Pull Credentials: 1. In a web browser go to registry1.dso.mil 2. Login via OIDC provider 3. Top right of the page, click your name –> User Profile 4. your username is what you’ll put into the file’s username spot 5. your CLI secret is what you’ll use as a password 6. There are 2 rectangles next to CLI secret, click it, and you’ll see green feedback “copy success” 7. Paste into a notepad 8. Click the 3 dots 9. Press Generate, a pop up will ask “Are you sure you can regenerate secret?” 10. Press Confirm, and you’ll see green feedback “Cli secret setting is successful” 11. Click the 2 rectangles next to the CLI secret, and you’ll see green feedback “copy success” 12. Paste into a notepad to verify the credentials have been rotated 13. Log into docker registry again shown below.

docker login registry1.dso.mil -u cmcgrath

The above command will prompt you for a password, that’s your new CLI secret from step 11

Task #7 Record your Registry1 IronBank Docker Image Pull Credentials💣

  • Write your Registry1 username and password into a text file
  • You will need to plug both sets of credentials into an encrypted config file in a future lab guide. (That lab guide will have a reminder saying that in this one you were supposed to write the creds into a text file for use in 5th lab guide’s 3rd lab.)

Task #8 Create a Repo1 Gitlab Personal Access Token💣

  1. Login to repo1.dso.mil/users/sign_in which has a register button if needed.
  2. In the top right of the GUI, click your user icon, a dropdown will appear, Select Settings
  3. In the Bottom Left of the screen you’ll see “>>”, which when clicked will change to “<< Collapse sidebar”
  4. Click “>>” to expand the sidebar, then click Access Tokens
  5. You’ll end up on this page: repo1.dso.mil/profile/personal_access_tokens
  6. Create a Personal Access Token
  7. It will ask you what scope you want the token to have, select all.
  8. It will ask you when you want the token to expire (have it expire 1 day from now, we won’t actually be using it as part of the labs, but it’s good info to know.)

The name can be arbitrary, but as a convention it’s best to have it match you’re username. When you click on the button that says [Create personal access token], it’ll show you the token which is effectively a password. There is no need to save or store the personal access token in a password manager, because it’s very easy to revoke and provision a new one. Note: You won’t use it as part of the labs, but it’s useful to know how to privision as it allows commiting to repos and accessing private repos.

Useful Background Info💣

Your newly rotated IB Docker Pull Credentials are still tied to a OIDC token, just an OIDC token created with offline flag so it lasts for 30 days vs 30 minutes. Thus you’ll want to login to the GUI once every 30 days to refresh it and prevent it from expiring. For production deployments ask your Big Bang Liaison or P1 Customer Success to request the Container Hardening Team provision an IronBank Robo Credential, which lasts for 6 months. Personal IB creds are intended for per user clusters, IronBank Robo Creds are intended for production deployments
