- Development Environment
Development Environment
Installing build dependencies
To setup a working local development environment, you must install the following minimum toolset:
If you're using MacOS or Linux, Make should be installed by default. If you are using Windows, you will need to install it separately. Additionally, if you would only like to run an in-memory instance of Kolide (for demonstrations, testing, etc.), then you do not need to install Docker.
Once you have those minimum requirements, you will need to install Kolide's dependent libraries. To do this, run the following:
make deps
When pulling in new revisions to your working source tree, it may be necessary
to re-run make deps if a new Go or JavaScript dependency was added.
Building
Generating the packaged JavaScript
To generate all necessary code (bundling JavaScript into Go, etc), run the following:
make generate
Automatic rebuilding of the JavaScript bundle
Normally, make generate takes the JavaScript code, bundles it into a single
bundle via Webpack, and inlines that bundle into a generated Go source file so
that all of the frontend code can be statically compiled into the binary. When
you build the code after running make generate, all of that JavaScript is
included in the binary.
This makes deploying Kolide a dream, since you only have to worry about a single
static binary. If you are working on frontend code, it is likely that you don't
want to have to manually re-run make generate and make build every time you
edit JavaScript and CSS in order to see your changes in the browser. To solve
this problem, before you build the Kolide binary, run the following command
instead of make generate:
make generate-dev
Instead of reading the JavaScript from a inlined static bundle compiled within
the binary, make generate-dev will generate a Go source file which reads the
frontend code from disk and run Webpack in "watch mode".
Note that when you run make generate-dev, Webpack will be watching the
JavaScript files that were used to generate the bundle, so the process will be
long lived. Depending on your personal workflow, you might want to run this in a
background terminal window.
After you run make generate-dev, run make build to build the binary, launch
the binary and you'll be able to refresh the browser whenever you edit and save
frontend code.
Compiling the Kolide binary
Use go build to build the application code. For your convenience, a make
command is included which builds the code:
make build
It's not necessary to use Make to build the code, but using Make allows us to
account for cross-platform differences more effectively than the go build tool
when writing automated tooling. Use whichever you prefer.
Managing Go Dependencies with Glide
Glide is a package manager for third party Go libraries. See the "How It Works" section in the Glide README for full details.
Installing the correct versions of dependencies
To install the correct versions of third package libraries, use glide install.
glide install will use the glide.lock file to pull vendored packages from
remote vcs. make deps takes care of this step, as well as downloading the
latest version of glide for you.
Adding new dependencies
To add a new dependency, use glide get [package name]
Updating dependencies
To update, use glide up which will use VCS and glide.yaml to figure out the correct updates.
Testing application code with glide
Testing
Full test suite
To execute all of the tests that CI will execute, run the following from the root of the repository:
make test
It is a good idea to run make test before submitting a Pull Request.
Go unit tests
To run all Go unit tests, run the following:
make test-go
JavaScript unit tests
To run all JavaScript unit tests, run the following:
make test-js
Go linters
To run all Go linters and static analyzers, run the following:
make lint-go
JavaScript linters
To run all JavaScript linters and static analyzers, run the following:
make lint-js
Viewing test coverage
When you run make test or make test-go from the root of the repository, test
coverage reports are generated in every subpackage. For example, the server
subpackage will have a coverage report generated in ./server/server.cover
To explore a test coverage report on a line-by-line basis in the browser, run the following:
# substitute ./datastore/datastore.cover, etc
go tool cover -html=./server/server.cover
To view test a test coverage report in a terminal, run the following:
# substitute ./datastore/datastore.cover, etc
go tool cover -func=./server/server.cover
Testing email using MailHog
To intercept sent emails while running a Kolide development environment, make
sure that you've set the SMTP address to <docker host ip>:1025 and leave the
username and password blank. Then, visit <docker host ip>:8025 in a web
browser to view the MailHog UI.
For example, if docker is running natively on your localhost, then your mail
settings should look something like:
mail:
address: localhost:1025
localhost:1025 is the default configuration. You can use kolide config_dump
to see the values which Kolide is using given your configuration.
Viewing email content in the terminal
If you're running Kolide in dev mode, emails will be printed to the terminal instead of being sent via an SMTP server. This may be useful if you want to view the content of all emails that Kolide sends.
Development infrastructure
Starting the local development environment
To set up a canonical development environment via docker, run the following from the root of the repository:
docker-compose up
This requires that you have docker installed. At this point in time, automatic configuration tools are not included with this project.
Stopping the local development environment
If you'd like to shut down the virtual infrastructure created by docker, run the following from the root of the repository:
docker-compose down
Setting up the database tables
Once you docker-compose up and are running the databases, you can build
the code and run the following command to create the database tables:
kolide prepare db
Running Kolide
Using Docker development infrastructure
To start the Kolide server backed by the Docker development infrasturcture, run the Kolide binary as follows:
kolide serve
By default, Kolide will try to connect to servers running on default ports on localhost.
If you're using Docker via Docker Toolbox.
you may have to modify the default values use the output of docker-machine ip
instead of localhost.There is an example configuration file included in this
repository to make this process easier for you. Use the --config flag of the
Kolide binary to specify the path to your config. See kolide --help for more
options.
Using no external dependencies
If you'd like to launch the Kolide server with no external dependencies, run the following:
kolide serve --dev
This will use in-memory mocks for the database, print emails to the console, etc. If you're demo-ing Kolide or testing a quick feature, dev mode is ideal. Keep in mind that, since everything is in-memory, when you kill the process, everything you did in dev mode will be lost. This is nice for development but not so nice for production environments.
If you've used make build to build the Kolide binary, you can also run the
following to launch an in-memory instance of the server:
make run
