Lets Encrypt has removed their ACME V1 api in favor of ACME V2. The Rancher 1.6 catalog entry for Lets Encrypt certificates doesn't support this api. There is a forked version of the repo, however the service has to be created manually instead of from the catalog.

1. Create a new service, give it a name, use vxcontrol/rancher-letsencrypt:v1.0.0 for the image
2. In the "Volumes" tab, add a volume /var/lib/rancher:/var/lib/rancher
3. In the "Command" tab, set the "Console" option to none
4. Click to add an Environment Variable, and paste the following into the first "Variable" input field.

• All of the environment variables should auto-fill.
• Fill in the necessary values

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.
