## Vagrant build environment
|
|
||||||
|
|
||||||
This provides a vagrant box for building the C++ side of Ml (and the Java side,
|
|
||||||
although that is easily accomplished outside vagrant).
|
|
||||||
|
|
||||||
Provisioning the box will take a fair amount of time, since it needs to download
|
|
||||||
and compile a number of dependencies.
|
|
||||||
|
|
||||||
|
|
||||||
### Details
|
|
||||||
- Ubuntu Trusty64 (14.04.5 LTS)
|
|
||||||
- 25% of host's memory
|
|
||||||
- 100% host's cores
|
|
||||||
- Maps ml source repository to `/home/vagrant/ml/src`
|
|
||||||
- Directory is shared with the host, so you can point your IDE to the ml repo
|
|
||||||
and build inside vagrant
|
|
||||||
- Maps ml build directory to `/home/vagrant/ml/build`
|
|
||||||
- Changes into `/home/vagrant/ml/src` on login
|
|
||||||
|
|
||||||
### Pre-baked box
|
|
||||||
Don't feel like compiling the entire box? No fear, there's a pre-baked box available
|
|
||||||
on S3. It is ~1.1gb to download:
|
|
||||||
|
|
||||||
```bash
|
|
||||||
# Change into some random directory to download the box.
|
|
||||||
# Doesn't matter where this goes, but *cannot* go into prelert-legacy/vagrant
|
|
||||||
$ cd ~/some_directory
|
|
||||||
|
|
||||||
# Export the path to your prelert-legacy repo. This is so the box knows where
|
|
||||||
# to sync the folders
|
|
||||||
$ export ML_SRC_HOME=/path/to/prelert-legacy
|
|
||||||
|
|
||||||
# Download the box from S3
|
|
||||||
$ s3cmd get s3://ml-elastic-dump/ml_env.box
|
|
||||||
# ...
|
|
||||||
# Downloading...
|
|
||||||
# ...
|
|
||||||
|
|
||||||
$ vagrant box add ml ml_env.box
|
|
||||||
$ vagrant init ml
|
|
||||||
$ vagrant up
|
|
||||||
$ vagrant ssh
|
|
||||||

vagrant@vagrant-ubuntu-trusty-64:~/ml/src$
|
|
||||||
```
|
|
||||||
|
|
||||||
Once you've logged into the box, you'll be in the ml source directory. You
|
|
||||||
can build immediately via:
|
|
||||||
|
|
||||||
```bash
|
|
||||||
vagrant@vagrant-ubuntu-trusty-64:~/ml/src$ gradle cppmake
|
|
||||||
```
|
|
||||||
The pre-baked box has already compiled ml once, so subsequent compilations
|
|
||||||
should happen considerably faster.
|
|
||||||
|
|
||||||
### Compiling from Scratch
|
|
||||||
|
|
||||||
If you feel like compiling everything from scratch instead of downloading the pre-baked
|
|
||||||
box, simply `vagrant up` and let the provisioners run:
|
|
||||||
|
|
||||||
```bash
|
|
||||||
$ cd prelert-legacy/vagrant
|
|
||||||
$ vagrant up
|
|
||||||
# ...
|
|
||||||
# wait while vagrant provisions
|
|
||||||
# ...
|
|
||||||
$ vagrant ssh
|
|
||||||

||||||

|
|
||||||
# ...
|
|
||||||
# much building
|
|
||||||
# ...
|
|
||||||
```
|
|
||||||
|
|
||||||
### Suspending your box
|
|
||||||
Once you've provisioned a box, you can use `vagrant suspend` to "sleep" the box.
|
|
||||||
This has the advantage of rebooting quickly when you `vagrant up`, and returns you
|
|
||||||
to exactly what you were doing. On the downside, it eats more disk space since it
|
|
||||||
needs to sleep the entire image.
|
|
||||||
|
|
||||||
You can alternatively use `vagrant halt`, which gracefully powers down the machine.
|
|
||||||
Rebooting via `vagrant up` takes longer since you are rebooting the entire OS,
|
|
||||||
but it saves more disk space.
|
|
||||||
|
|
||||||
### Fixing a broken box
|
|
||||||
If you accidentally kill the provisioning process before it completes, you can
|
|
||||||
attempt to reprovision it with `vagrant reload --provision`. That will run
|
|
||||||
the provisioners that did not complete previously.
|
|
||||||
|
|
||||||
If your box is still horribly broken, you can destroy it with `vagrant destroy`
|
|
||||||
and try again with `vagrant up`
