Contains a fully reproducible configuration for JupyterHub on datahub.berkeley.edu, as well as its single user image.
The staging branch always reflects the state of the staging JupyterHub,
and the prod branch reflects the state of the production JupyterHub.
First, go to your github profile settings and make sure you have an SSH key uploaded.
Next, go to the Datahub github repo
and create a fork. To do this, click on the fork button and then Create fork.
Now clone the primary Datahub repo on your local device. You can get the URL to do
this by clicking on the green Code button in the primary Datahub repo (not your fork)
and clicking on ssh:
git clone git@github.com:berkeley-dsep-infra/datahub.git
Now cd in to datahub and set up your local repo to point both at the primary
Datahub repo (upstream) and your fork (origin). After the initial clone,
origin will be pointing to the main repo and we'll need to change that.
$ cd datahub
$ git remote -v
origin git@github.com:berkeley-dsep-infra/datahub.git (fetch)
origin git@github.com:berkeley-dsep-infra/datahub.git (push)
$ git remote rename origin upstream
$ git remote add origin git@github.com:<your github username>/datahub.git
$ git remote -v
origin git@github.com:<your github username>/datahub.git (fetch)
origin git@github.com:<your github username>/datahub.git (push)
upstream git@github.com:berkeley-dsep-infra/datahub.git (fetch)
upstream git@github.com:berkeley-dsep-infra/datahub.git (push)
Now you can sync your local repo from upstream, and push those changes to your
fork (origin):
git checkout staging && \
git fetch --prune --all && \
git rebase upstream/staging && \
git push origin staging
When developing for this deployment, always work in a fork of this repo. You should also make sure that your repo is up-to-date with this one prior to making changes. This is because other contributors may have pushed changes after you last synced with this repo but before you upstreamed your changes.
git checkout staging && \
git fetch --prune --all && \
git rebase upstream/staging && \
git push origin staging
To create a new branch and switch to it, run the following command:
git checkout -b <branch name>
After you make your changes, you can use the following commands to see
what's been modified and check out the diffs: git status and git diff.
When you're ready to push these changes, first you'll need to stage them for a commit:
git add <file1> <file2> <etc>
Commit these changes locally:
git commit -m "some pithy commit description"
Now push to your fork:
git push origin <branch name>
Once you've pushed to your fork, you can go to the
Datahub repo and there
should be a big green button on the top that says Compare and pull request.
Click on that, check out the commits and file diffs, edit the title and
description if needed and then click Create pull request.
If you're having issues, you can refer to the github documentation for pull
requests.
The choice for base in the GitHub PR user interface should be the staging
branch of this repo while the choice for head is your fork.
Once this is complete and if there are no problems, you can request that someone review the PR before merging, or you can merge yourself if you are confident. This merge will trigger a CircleCI process which upgrades the helm deployment on the staging site. When this is complete, test your changes there. For example if you updated a library, make sure that a new user server instance has the new version. If you spot any problems you can revert your change. You should test the changes soon after the merge since we do not want unverified changes to linger in staging.
If staging fails, never update production. Revert your change or
call in help if necessary. If your change is successful, you will need
to merge the change from staging branch to production. Create another PR,
this time with the base set to prod and the head set to staging. This
PR will trigger a similar Travis process. Test your change on production
for good measure.
