Accepting Chef Infra Client license agreement for version >= 14

I'm trying to bootstrap a node using chef by using the command knife bootstrap <host> --ssh-user '<username>' -i <my-identity>.pem --sudo --use-sudo-password --node-name <node-name> --run-list 'recipe[<cookbook-name>::default]'

However, its failing because I can't accept the license

137.252.24.94
137.252.24.94 Do you accept the 2 product licenses (yes/no)?

And I can't input the answer from the host machine. I used to be able to run the chef boostrap command easily before chef 14.0. It seems like they upgraded to Chef 14.0 and the new upgrade has a mandatory requirement for the license agreement. How do I agree the license into the client machine from the host machine?

Solution

Basically, based on my findings, this problem can occur in two different scenarios:

When you're running the kitchen converge. This can be solved very easily by adding a piece of code inside the kitchen.yml as
```
provisioner:
  client_rb:
    chef_license: accept
```
When you're running the knife bootstrap, this can be a little bit of extra work. This page explains all that needs to be done. Inside the .chef directory.

> mkdir bootstrap
> cd bootstrap && touch template.erb
> find /opt/chefdk/embedded/lib/ruby -type f -name chef-full.erb -exec cat {} \; > template.erb

Find the line that part that says

cat > /etc/chef/client.rb <<'EOP
<%= config_content %>
EOP

and replace it with

cat > /etc/chef/client.rb <<'EOP'
<%= config_content %>
chef_license "accept"
EOP

Next, run the command knife bootstrap <host> --ssh-user '<username>' -i <my-identity>.pem --sudo --use-sudo-password --node-name <node-name> --boostrap-template "template" --run-list 'recipe[<cookbook-name>::default]'. That took care of it.
