Project: Building a Chef 12 Server on DigitalOcean

Getting all system updates applied before getting down to business.

Downloading Chef 12.1.2 now.

https://web-dl.packagecloud.io/chef/stable/packages/ubuntu/trusty/chef-server-core_12.1.2-1_amd64.deb

scottalanmiller

Install command:

sudo dpkg -i chef-server-core_12.1.2-1_amd64.deb

scottalanmiller

There was a warning in the DO instructions here: This will install the base Chef 12 system onto the server. If you have selected a server with less powerful hardware than the recommended amount, this step may fail.

But even on this little single core, 1GB RAM Droplet everything appears to have gone smoothly, no errors were generated.

I always add a few extra packages of my own:

sudo apt-get install htop sysstat fail2ban

Turn on SAR data collection:

sudo vi /etc/default/sysstat

Set the value of ENABLED to true.

Because we are creating an instance that is so tiny and tight on resources, it would be smart to set up some swap space right from the beginning to make sure that we are as well situated as possible. This is a pretty standard procedure but DigitalOcean actually has a specific How To made for this specific to Ubuntu 14.04.

https://www.digitalocean.com/community/tutorials/how-to-add-swap-on-ubuntu-14-04

sudo fallocate -l 3G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile

scottalanmiller

You will want to make that swap file permanent too:

echo "/swapfile   none    swap    sw    0   0" >> /etc/fstab

Next up, reconfiguring chef:

sudo chef-server-ctl reconfigure

This step takes several minutes to run, so don't be surprised.

Now it is time to create an admin user. Of course, you will need to modify this command for your own purposes.

chef-server-ctl user-create USERNAME FIRST_NAME LAST_NAME EMAIL PASSWORD

scottalanmiller

This last step will output a private key. Make sure to save this before going on to do anything else.

Now to make our first organization, we will make a test one to get started.

chef-server-ctl org-create SHORTNAME LONGNAME --association_user USERNAME -f filename

That's the format, here is a real command:

chef-server-ctl org-create test "Chef Testing NonProd" --association_user scott -f scott.pem
