Hi, Currently our company has +/- 50 apps where every app has its own data-area on NFS. We need to switch S3, using Ceph, as our new data layer with every app using its own s3-bucket, equivalent to the NFS data-area. The sizes of the data-areas, depending on the app, varies from 1.3 GB to 358 GB.
In order to test multiple versions of the app, we currently make a writable snapshot of the data-area to avoid copying or 'polluting' the original (i.e. 'production' data). Since a snapshot is fast we can make multiple snapshots easy and discard them afterwards. With Ceph, we would like to do something alike, i.e. 'fast' copying and easily discardable. The path we are trying to take is: make a 'clone' of the bucket (i.e. writable snapshots) into a test-bucket. Our design for this is the following: - We need to have every app bucket in its own unique pool-set. - (on the ceph-nodes) determine the pool-set that is used by the given bucket - (on the ceph-nodes) make snapshots of the pools and assign these snapshots to an newly created (writable!) test-bucket. - after the test is finished, the test-bucket can be removed (either from the ceph-node or the test system). The test-procedure that is testing the app is aware of its environment, i.e.: it 'knows' that it has to do specials things to get a test-bucket. The app itself isn not aware of this, and just uses whatever bucket is passed to it. This way the test procedure can use the test-bucket and does not interfere with the original data and the app can be run 'as-is' without changing the code. I have the following question: Is this scenario at all possible? - if yes: how can I accomplish this? - if no: is this a design-flaw (it can be done, just not this way) or its simply not possible. -- Best regards, Fred Gansevles /Devops Engineer/ <https://www.betterbe.com> Auke Vleerstraat 140 E *T* +31 (0) 53 48 00 680 <tel:+31%20%280%29%2053%2048%2000%20680> 7547 AN Enschede *E* fgansev...@betterbe.com <mailto:fgansev...@betterbe.com> CC no. 08097527 <https://www.kvk.nl/orderstraat/product-kiezen/?kvknummer=080975270000> *M* +31 (0)6 30 262 174 <tel:+31%20%280%296%2030%20262%20174> www.betterbe.com <https://www.betterbe.com> BetterBe accepts no liability for the content of this email, or for the consequences of any actions taken on the basis of the information provided, unless that information is subsequently confirmed in writing.
