Dmitrii Shcherbakov 009c8a7b92 Dynamically generate proxy settings for image syncs ... sstream-mirror-glance has several endpoints it needs to talk to: * Image mirrors - typically, public Internet endpoints; * Keystone - typically, a directly reachable endpoint; * Glance - typically, a directly reachable endpoint; * Object store (Swift) - typically, a directly reachable endpoint but sometimes it may be deployed externally and added to the region catalog in Keystone (in which case it might be accessible via a proxy only). While sstream-mirror-glance does not support specifying proxy settings for individual directions, since we know all of them based on the Keystone catalog, a list of endpoints to add to NO_PROXY environment variable can be generated dynamically. The complication is that image syncs are periodically done via a cron job so a juju-run invocation is needed to retrieve relevant proxy settings from model-config at each invocation of the synchronization script. Additionally, the charm is long-lived so there may be some environments that rely on legacy proxy settings. This change accounts for that and acts both on juju-prefixed (new) and unprefixed (legacy) proxy settings. Whether to use proxy settings for connections to the object store API is controlled by a charm option which the script is made to react to. Proxy settings are ignored for object store connections by default. Closes-Bug: #1843486 Change-Id: Ib1fc5d2eebf43d5f98bb8ee405a3799802c8b8dc		2021-07-22 21:14:03 +03:00
