Cache and freshness
It can be harmful to the server to run all checks on each HTTP endpoint call, so a cronjob in background is writing results, and HTTP endpoint is reading.
How often really the checks are performing depends on your configuration, how often you execute infracheck --force
The --force parameter means that the application will write checks results to a cache.
When this flag is not specified, then application will read the data from the cache.
If you use an official docker image, then you can set CHECK_INTERVAL to a crontab-like syntax interval eg. CHECK_INTERVAL=00 23 * * * to check once a day (good for domains whois check).
Some checks could call external APIs, those can have limits. A good example is a domain-expiration check which is using whois. It is recommended to run a separate infracheck instance with less frequent checking, eg. once a day - see CHECK_INTERVAL in docker, and crontab in standalone installation.
You can also use --wait switch to set waiting in seconds between single checks (in docker it is WAIT_TIME variable)
When running a ex. HTTP endpoint without --force, then application is only reading results of previously executed checks that are usually executed in background using cron. Without lazy the checks that were not executed yet will be showing "Not ready yet" and a status equals to false. If you really need to avoid such case, then you can allow running a check on-demand by enabling --lazy flag (LAZY=true in docker).
