Leonardo Mörlein 24ddf22073 uacme: add retries ... Prior to this commit, the acme service attempted to obtain certificates once and then terminated, regardless of whether the certificate could be obtained or not. This commit introduces a new uci option "retries" to the "certificate" section. If this option is set to N, the acme service will attempt to obtain the certificate up to N times before terminating. There is a waiting pause between the retries to comply with the rate limits of Let'sEncrypt. The waiting pause is: - 2 minutes for staging certificates - 24 minutes for production certificates The current "Failed Validation" rate limits of Let'sEncrypt are: - staging: 60 per hour -> 1 failure every 1 minute in avg. - production: 5 per hour -> 1 failure every 12 minutes in avg. This means that we are within rate limits by a factor of two. By default the option "retries" is set to "1", which means that acme behaves as before by default. If the variable is set to "0", infinite retries are performed. This feature is helpful, when you already want to initiate the certificate request, but you are still waiting for your dns server to be configured, your network to appear or other conditions.
