Uses local RPM build for "dev" and "staging" scenarios #587

Description of Changes

Fixes #538

Changes proposed in this pull request:

Using the "make dev" environment now uses RPMs for install/uninstall
Docker is now required in the dev env!

Hopefully this will make reasoning about problems like #505 a lot more accessible to developers.

Testing

Requesting testing for multiple scenarios, since early review showed some surprises.

Dev scenario

There's a catch here—you must run make clone twice in order to get started, because the first clone will only pull in the new docker logic, not run it.

make clone
make clone # [sic]
make clean # ensure everything removed cleanly
make dev
make test

Mess around with the clean/clone/dev/test combinations and see if you can get anything to break.

Staging scenario

Now let's check that "staging" scenario continues to work well. Notably the locally built RPM will be installed in staging.

make clone
make clone # [sic, just in case you didn't already run it twice for dev]]
make clean # ensure everything removed cleanly
make staging

Interact, confirm staging-specific functionality like shutdown-on-lid close is working, then run make clean to clean up and confirm no errors.

Prod scenario

Since the prod flow uses a separate setup process (https://workstation.securedrop.org/en/stable/admin/install.html#download-and-install-securedrop-workstation), there shouldn't be any conflicts with the logic presented here. If you can think of some, please comment or directly edit this test plan!

Marking as ready-for-review. Rebased these changes and tested locally, and was pleased with the results, so it's ready for more eyes.

+    printf "Building RPM on %s ...\n" "${dev_vm}"
+    qvm-run -q "$dev_vm" "make -C $dev_dir dom0-rpm"


would it make sense here to bump the RPM version to make sure that the version is always higher than anything available?

I'm not aware of any RPM tooling like dch for programmatically bumping the version. Ideally it'd be something like <current_version><alpha1><git_short_hash>, but absent tooling, simply defaulting to <current_version> makes the most sense to me.

emkll

Went through this again, from a development scenario perspective, changes look good and are a significant improvement for developers and brings more consistency across environments.

However it looks like there might be some implications for prod/staging scenarios (see inline). It might make sense to only invoke prep-salt exclusively for the dev scenario (instead of conditionals).

There's also a potential versioning issue: if the version of the local RPM is lower than the one served by the rpm repo, changes to the salt files may be overwritten by the ones on the RPM servers. We can autoupdate but we can also just provide a docs update to unblock, since this will only affect developers.

Finally, tests rely on the create_tarball function https://github.com/freedomofpress/securedrop-workstation/pull/587/files#diff-3c3ec2225864916f85515009ebeeb428L24 . Packaging the tests and reducing/eliminating the requirement of a full clone of the repository in dom0 may help reduce developer error (changes to salt files in the dom0 securedrop-workstation folder will effectively be useless). I don't think this should be immediately addressed as part of this PR, but should probably be tracked in a follow-up issue

UPDATE: we will need to rebase and update references to the installer (securedrop-admin -> sdw-admin since #596 has been merged)

(Needs rebase after #596)

Builds the RPM in sd-dev VM, then fetches it to dom0 for local installation via the make-clone action. Simplifies the provisioning logic by trusting dnf to handle the add/remove of all config files. Adjusts the docker build command, removing flag for interactive session. In order to run the build via qvm-run from dom0, we must remove the flag, otherwise `docker run` fails with: the input device is not a TTY There are no prompts in the rpm build process.

Now we use the RPM to manage presence/absence of all scripts and configs, Salt or otherwise. So we don't want to double-remove the files, we'll trust the "dnf remove" action to handle it, regardless of environment (dev, staging, or prod).

Adjusts the "make clean" target to reuse the local securedrop-admin script for provisioning. Added two new cli flags to the script, both off by default, to accommodate dev-scenario settings: --keep-template-rpm (to avoid time spent redownloading) and --force (to avoid prompts).

Previously it was emitting helpful text, but still exiting zero, so when used in chains like "make all && make test" it would try to continue processing.

@emkll

Pointed out by @emkll during review: the "staging" and "prod" makefile targets were including "prep-salt", but they really don't need to. So, removing them, and renaming the target accordingly.

Per our discussion at standup, I've added a commit 9dc287a that updates the staging target to use a locally built RPM, just like the dev target. The intended remaining use of this target is during the development of RCs, and to test differences in behavior that are specific to staging (e.g., the power management settings) during development.

That commit also removes the prod target in its entirety, since it serves no obvious purpose at this point. I've tested make staging locally and it seems to work, and I've updated the README, but I haven't updated the test plan yet. @conorsch If this commit looks good to you, I can flesh out the test plan a bit.

While nightly RPMs are currently "temporarily" disabled, I would propose to block merge of this PR until freedomofpress/securedrop-builder#186 is resolved, as the current CircleCI configuration still suggests that we may want to re-enable nightly RPM builds at a later date, which would be unsafe to do in combination with this change.

emkll

Thanks @conorsch and @eloquence. I have tested both the staging and dev environments locally, left a few notes inline mostly related to documentation. I think this is otherwise good to squash and promote for final review/merge

your package repository configuration will be updated to use the latest test release of the RPM package

This could be somewhat misleading. If the version of the locally built package is equal or higher than the one mirrored by yum-test, the latest test release of the RPM package will not be used (but it will receive test package updates). We should specify to use the prod install procedures to fully mirror the prod flow (or ensure the RPM is build off the latest tag/rc when cloning the repo in the dev VM). (related to comment in https://github.com/freedomofpress/securedrop-workstation/pull/587/files#r458880338)

Fair point. Rephrased as:

As part of the provisioning, a locally built RPM will be installed in dom0. The dom0 package repository configuration will be updated to install future test-only versions of the RPM package from the https://yum-test.securedrop.org repository, and Workstation VMs will receive the latest nightlies of the Debian packages (same as make dev).

We should state here that the rpm package is built in the dev env. We should also include a note stating that Docker is now strictly required in the Dev VM

This is stated in the setup instructions for sd-dev:

You must install Docker in that VM in order to build a development environment using the standard workflow.

But I agree a parenthetical here won't hurt as well, will add a commit to that effect.

If I understand correctly, here we are explicitly excluding dev from installing the RPM to avoid installing the latest from the yum repos should the locally built version be lesser than the ones on the server. if that's the case, it may be worth adding a comment here for future maintainers as it is somewhat counter-intuitive.

The changes to the dev environment may have repercussions on these individual makefile targets :

prep-salt makefile target would copy the local salt file in /srv/salt/ whereas this updated prep-dev target will install the dom0 rpm. This means that any changes to the local files in the securedrop-workstation folder in dom0 will not be used.

If this is the case, adding a note to this effect in the dev docs could be helpful

If this is the case, adding a note to this effect in the dev docs could be helpful

That's definitely true. Editing the files in e.g. /srv/salt/ still works fine, but I wouldn't recommend either, given how easy it is to lose changes that way. Will clarify in the docs!

conorsch · 2020-09-01T18:36:48Z

@zenmonkeykstop You're right, there are a bunch of import "sd/config.json" calls in the Salt files. The "import" path evaluates to /srv/salt/sd/config.json, but in other contexts such as the prod docs, we assume that /usr/share/securedrop-workstation-dom0-config/config.json is the proper path. We should definitely fix this, but it looks to my eye like that's a problem on main branch, too.

zenmonkeykstop · 2020-09-01T19:38:40Z

config.json gets copied to /srv/salt/sd by the make dev/staging runs though, so the issue here IMO is more that make clean doesn't run cleanly when there isn't an existing install or the install broke before that point. If it's run before the RPM is installed then there won't be anything under /usr/share/securedrop... either.

conorsch · 2020-09-01T19:44:24Z

config.json gets copied to /srv/salt/sd by the make dev/staging runs though

That's no longer true on this branch, which doesn't copy the files to /srv/salt/ anymore.
In prod contexts, we tell admins to configure the secrets in /usr/share/, with no mention of /srv/salt/ at all.

Since Salt state files require access to the json file to import, we should be using the /usr/share/ path in all places as of this PR, since this PR uses the RPM everywhere, even for make-dev. I'll push up a commit making that change.

If it's run before the RPM is installed then there won't be anything under /usr/share/securedrop... either.

Unintuitive, but running 'make clean' will actually install the rpm, then remove everything, because the files for removal are installed by the RPM. That's not new in this PR, that's true even on the main branch now, where "prep-salt" is run as a dependency of make-clean.

The salt states require secrets such as the config file and privkey to be stored in `/srv/salt/sd/`, as the import lines in the state files assume those locations. The sdw-admin install action copies those files into place, but in the case of "make clean", the secrets won't be there. Let's make sure they are, and make sure to remove them (as on main) via the uninstall action.

conorsch · 2020-09-02T15:41:03Z

@zenmonkeykstop The latest commit now supports make-clean even when no prior installation has been run. I did not move the import locations, preferring /usr/share/, but rather re-added the copy-to-srv-salt logic. There are two secrets, the privkey and the config.json file, and the privkey needs a "salt:// prefix (and therefore must be inside /srv/salt/, so it wasn't worth moving just one file. The sdw-admin "install" action copies the files into place in /srv/salt on each run, and both the sdw-admin "uninstall" and the make-clean actions remove them from /srv/salt.

Was still used by sdw-admin, so we must keep it around, even if it's not useful in the raw Makefile targets.

Follow up to #587. The `dnf install -y <local_file>` action will not reinstall a package if the versions are the same. Since we expect package contents to change, but not version strings, when running `make clone`, let's make sure to uninstall the rpm package in dom0 so that the install action always takes effect.
