GitHub - getsentry/devenv: unified dev environment management tool

devenv

managing dev environments since '24

devenv is an extensible execution framework and library for authoring a simple set of high level commands - bootstrap, sync, doctor, nuke - that manage a repository's dev environment.

prerequisites

Are you a Sentry employee? Make sure your GitHub account has been added to a getsentry/engineering team. If not, open an IT Ticket before continuing.

Otherwise, set the SENTRY_EXTERNAL_CONTRIBUTOR environment variable.

install

Download this and run it:

bash install-devenv.sh

This "global" devenv is installed to ~/.local/share/sentry-devenv/bin/devenv.

To update this installation, run devenv update.

user guide

devenv bootstrap

This is intended for initial setup of a new machine.

devenv fetch [repository name]

Any repository on github in the form of [org]/[reponame]

Repositories are cloned to a "coderoot" directory which is specified in the global configuration.

Note: sentry and ops are currently special names which perform more complicated installations (e.g., sentry will set up both sentry and getsentry)

devenv sync

This runs a user-supplied [reporoot]/devenv/sync.py which should:

make sure any desired tools are installed
bring the dev environment up-to-date, or create it if it doesn't exist

This script runs within devenv's runtime, which has access to many useful high-level routines. There are currently no api docs, but referring to the examples should get you 90% of the way there.

If you have a feature request, please open an issue!

In general, our library is designed to isolate, as much as possible, a repo's dev environment within [reporoot]/.devenv. For example, gcloud is installed to [reporoot]/.devenv/bin/gcloud (with the gcloud sdk at [reporoot]/.devenv/bin/google-cloud-sdk). An exception to this would be python virtualenvs, which was implemented before the idea of [reporoot]/.devenv.

devenv doctor

When you're inside a repository, this diagnoses and tries to fix common issues. Checks and fixes are defined in [reporoot]/devenv/checks.

devenv nuke|uninstall (wip)

When you're inside a repository, this completely removes the dev environment.

technical overview

Everything devenv needs is in ~/.local/share/sentry-devenv.

~/.local/share/sentry-devenv/bin contains devenv and direnv
- we currently rely on a minimal [reporoot]/.envrc to add [reporoot]/.devenv/bin to PATH
- see examples for .envrc suggestions

runtime

devenv is installed exclusively in a virtualenv at ~/.local/share/sentry-devenv/venv
- this venv exclusively uses a python at ~/.local/share/sentry-devenv/python

global configuration

~/.config/sentry-devenv/config.ini

[devenv]
# the parent directory of all devenv-managed repos
coderoot = ~/code

repository configuration

[reporoot]/devenv/config.ini

[devenv]
# optionally require a minimum version to run sync.py
minimum_version = 1.11.0

There are plenty more sections, their use is best seen in the examples.

examples

Skip to:

direnv
python
node
brew
colima
gcloud
terraform

direnv

A minimum viable [reporoot]/.envrc is currently needed:

if [[ -f "${PWD}/.env" ]]; then
    dotenv
fi

PATH_add "${HOME}/.local/share/sentry-devenv/bin"

if ! command -v devenv >/dev/null; then
    echo "install devenv: https://github.com/getsentry/devenv#install"
    return 1
fi

PATH_add "${PWD}/.devenv/bin"

python

Need a single virtualenv (or have one already at .venv you want devenv to manage?)

[reporoot]/.envrc

export VIRTUAL_ENV="${PWD}/.venv"

PATH_add "${PWD}/.venv/bin"

[reporoot]/devenv/sync.py

    url, sha256 = config.get_python(reporoot, python_version)
    print(f"ensuring venv at {venv_dir}...")
    venv.ensure(venv_dir, python_version, url, sha256)

You can also have multiple virtualenvs, which is useful if you rely on a python tool that has a bunch of dependencies that may conflict with others.

terraform

Our responsibility ends at installing tenv and containing TENV_ROOT at [reporoot]/.devenv/bin/tenv-root. We install terraform and terragrunt shims which use that TENV_ROOT.

Define [reporoot]/.terraform-version and [reporoot]/.terragrunt-version (if you want it) and after running sync, you should be able to just type terraform and tenv takes care of the rest.

We use tox. The easiest way to run devenv locally is just using the tox venv's executable:
