do3meli | hi there - i just came across mistral and looks like it is a very useful tool for me. the only question i couldn't answer myself so far is: "why does heat still exists when i can achieve the same with mistral?" | 08:15 |
d0ugal_ | rakhmerov: sure | 08:26 |
d0ugal_ | do3meli: they have some similarities, but they are quite different. | 08:26 |
rakhmerov | d0ugal_: thanks! | 08:26 |
rakhmerov | d0ugal_: yes, I'd say completely different approaches | 08:27 |
d0ugal_ | do3meli: we use Heat and Mistral :) | 08:27 |
do3meli | d0ugal_: allright, thanks. i am still bit confused. so whats the benefit for me if i still maintain heat while having mistral installed? will i loose any feature? as far as i can tell by now mistral is able of handling all the things heat can + much more (which is why i take mistral as a replacment) | 08:29 |
d0ugal_ | I am trying to think of the best way to explain this. | 08:30 |
d0ugal_ | one sec | 08:31 |

rakhmerov | :) | 08:31 |
d0ugal | rakhmerov: do you know if anyone has written up an answer to this before? | 08:31 |
rakhmerov | d0ugal: not that I could provide as a reference | 08:34 |
rakhmerov | do3meli: so, Heat is "what to do" and Mistral is "how to do" | 08:34 |
rakhmerov | in Heat you describe your environment (a target state) and it will create this environment for you | 08:35 |
rakhmerov | for Mistral a process (concrete steps) are important, you describe them | 08:35 |
rakhmerov | rather than any target state | 08:35 |
d0ugal | Right, and Heat is idempotent like ansible/puppet etc. should be | 08:39 |
do3meli | ok - so given you say mistral describes concrete steps, does this mean i can not use mistral do describe my end state of an environment - meaning mistral will execute a task and will not verify the outcome of it against a certain state. | 08:39 |
d0ugal | do3meli: you could verify the outcome in a Mistral workflow, but it isn't something that it does by default | 08:40 |
do3meli | d0ugal: alright. so you said earlier you guys use both. heat and mistral. lets say you build a new open stack environment. would you still be using both or would you just go for mistral. functionality wise i can't see anything missing in mistral that heat would allow me to do. so other than a certain backwards compatibility i don't see a point of having both. | 08:47 |
d0ugal | do3meli: that is a hard question to answer :) | 08:48 |
d0ugal | do3meli: I work on TripleO but I am not very familiar with Heat or the tripleo-heat-templates | 08:48 |
do3meli | sorry d0ugal if i challange you ;-) | 08:49 |
d0ugal | haha | 08:49 |
d0ugal | so I probably don't have enough depth of knowledge to give you a full answer, but I suspect that we would use both if we were to start again. | 08:49 |
d0ugal | Our Heat templates are very comprehensive. https://github.com/openstack/tripleo-heat-templates | 08:49 |
d0ugal | I'm not sure I can imagine what that would look like in a Mistral only solution. | 08:50 |
d0ugal | sorry, that is a bit of a non-answer :) | 08:50 |
d0ugal | I guess, like most things, "it depends" | 08:51 |
*** bobh has joined #openstack-mistral | 08:51 | |
d0ugal | and in this case I think it depends how complex your usage of Heat and/or Mistral are. If they are relatively simple then you can likely replicate what you need in the other | 08:51 |
d0ugal | In our case Mistral calls Heat and creates Heat stacks and Heat also triggers Mistral workflows. So they work well together. | 08:52 |
do3meli | :-) no worries. to be honest: i have a working heat system in place currently. and now need to talk to external api's in order to fulfill deployments of vm's (config management, monitoring, ect). so i guess i will be going the same road as you. having installed both. | 08:53 |
d0ugal | do3meli: cool, I would be interested to hear how you find it | 08:54 |
*** bobh has quit IRC | 08:56 | |
do3meli | sure ;) will see how it goes the next few days/weeks. as a side note: wouldn't this question be something for the https://wiki.openstack.org/wiki/Mistral#FAQ ? | 08:58 |
do3meli | i see btw one benefit of still having heat templates while using mistral: havin a heat template makes it easy to see what belongs togehter. without that you would just have stand alone volumes, vms, ect. with heat you really see that in one shot ;) | 08:59 |
d0ugal | do3meli: yup, the comcept of a stack is useful - there is no good way to share and maintain state in Mistral over a long period like that. | 09:01 |
d0ugal | do3meli: I think we should try and answer this in the Mistral documentation, there is quite often confusion with new users about "what" and "why" | 09:02 |
