50 certificates for new sets of names.
This means that, for example, this domain https://fimlsgreat.tk/ has a limit of 50 new certificates per week?
If you’re running some kind of containerized environment, you should certainly save your Let’s Encrypt data to persistent storage, especially if you blow the containers away every time new commits are pushed or something.
I do not use containerized environment, I use VirtualBox to set up the environment development.
When the development environment will have been configured, the certificate will only be updated.
To set up a development environment, I need about 10 certificates per week. I use the cache, and I don’t have to install the certificate every time.
