[889.52 --> 893.64] But by default, you know, if you run that Linkerd install command, that generates a certificate |
[893.64 --> 894.70] that's only valid for a year. |
[894.88 --> 898.42] So you have a year then to figure out, okay, here's how I'm going to rotate it. |
[898.74 --> 898.86] Right. |
[898.86 --> 899.58] That's a good one. |
[899.64 --> 899.74] Yeah. |
[899.74 --> 901.32] That actually catches quite a few people. |
[901.54 --> 902.42] They don't think about that. |
[902.86 --> 902.96] Yeah. |
[902.96 --> 905.98] But maybe if you upgrade, does it get rotated part of the upgrade? |
[906.06 --> 907.08] Because that would solve the problem. |
[907.50 --> 907.94] No, it doesn't. |
[908.06 --> 910.88] No, it doesn't because I don't believe it does. |
[911.28 --> 911.94] Actually, I'm not sure. |
[912.28 --> 912.42] Yeah. |
[912.54 --> 912.74] Okay. |
[913.30 --> 917.02] But in addition to the issuer certificate, there's also the trust certificate or the trust route, |
[917.02 --> 919.48] which definitely doesn't get rotated as part of an upgrade. |
[919.62 --> 919.78] Yeah. |
[920.10 --> 921.62] And that also has a one-year expiration. |
[921.74 --> 924.92] So, you know, it is easy to install and it's easy to make things work. |
[924.92 --> 929.76] But like with any sophisticated piece of technology, as you push it into production, |
[929.96 --> 932.10] there's stuff that you need to be aware of. |
[932.28 --> 937.52] We actually wrote a runbook, a production runbook for Linkerd on buoyant.io. |
[937.68 --> 942.44] So if you want our advice as, you know, the company that has installed Linkerd and helped |
[942.44 --> 946.38] people operate Linkerd in a lot of different places, and in fact, we operate it ourselves. |
[947.10 --> 950.36] If you want our best advice for how to install it, you can read through the runbook and we talk |
[950.36 --> 953.40] about certificate rotation and some other things you want to be aware of. |
[953.58 --> 954.08] That's a good one. |
[954.08 --> 954.32] Okay. |
[954.34 --> 955.08] I didn't know about that. |
[955.14 --> 955.44] Thank you. |
[955.54 --> 957.22] That's a great, great tip. |
[957.48 --> 961.14] You got to make sure like you don't have clock skew between the nodes because, you know, |
[961.18 --> 962.60] all these TLS certificates. |
[963.08 --> 963.54] Oh, yes. |
[963.56 --> 964.80] You don't have time components. |
[964.80 --> 967.48] And if you've got big clock skew, then like things are not going to be able to connect |
[967.48 --> 967.98] even though they should. |
[968.22 --> 968.72] There's details. |
[968.82 --> 970.16] It turns out computers are complicated. |
[970.62 --> 972.74] As much as we try and simplify them, there's details. |
[973.02 --> 977.16] So I'm wondering, what are you looking forward to the most when it comes to KubeCon, |
[977.28 --> 978.78] this KubeCon, which is? |
[979.04 --> 980.40] Oh, for me, that's easy. |
[980.48 --> 982.14] And it's actually not really project. |
[982.14 --> 984.06] Well, it's kind of semi-project related. |
[984.48 --> 987.84] It's just being there in person with other human beings. |
[988.44 --> 989.90] Like for me, that's so gratifying. |
[990.50 --> 994.66] You know, I think open source can be a little isolating because a lot of your interactions |
[994.66 --> 999.92] with people are, they come into the, you know, in our case, the Slack channel and they're |
[999.92 --> 1000.88] like, hey, I have this problem. |
[1001.22 --> 1002.80] And then you like help them fix it. |
[1003.02 --> 1003.60] And they're like, thanks. |
[1003.60 --> 1004.18] And then they leave. |
[1004.56 --> 1006.88] And then the next person comes and presents you with another problem. |
[1006.98 --> 1009.84] And like, you develop this kind of transactional relationship. |
[1010.00 --> 1014.32] And what you don't see in that, which you do see in person, what you don't see on Slack |
[1014.32 --> 1017.80] is, oh, people then go off and they like deploy Linkerd and they're really successful. |
[1018.14 --> 1021.64] And their company is, you know, thankful and like everything's working well. |
[1021.86 --> 1024.14] They don't come back to the Slack to say, well, sometimes they do. |
[1024.14 --> 1025.58] But usually they're like, okay, cool. |
[1025.66 --> 1026.94] Now I can do the rest of my job. |
[1027.54 --> 1030.52] But in person, you know, when you talk to these people, you realize there actually are |
[1030.52 --> 1032.40] a ton of people who are running Linkerd. |
[1032.88 --> 1034.88] They're, you know, it's solving big problems for them. |
[1034.96 --> 1037.56] And now they have an opportunity to come up and tell you about that. |
[1037.92 --> 1040.44] So that aspect has always been really amazing for me. |
[1040.54 --> 1045.70] And the virtual conferences, you know, as much as I like the convenience of not having |
[1045.70 --> 1048.42] to hop on an airplane, they don't quite have that same thing. |
[1048.54 --> 1050.62] So that's the long answer to a short question. |
[1051.00 --> 1052.90] I'm looking forward to the human interaction. |
[1052.90 --> 1053.76] Oh, yes. |
[1053.96 --> 1054.52] Don't we all. |
[1054.82 --> 1055.32] Don't we all. |
[1055.72 --> 1055.88] Yeah. |
[1056.10 --> 1057.74] I wish there wasn't a screen today. |
[1059.00 --> 1059.60] About Linkerd. |
[1059.72 --> 1059.82] Yeah. |
[1060.12 --> 1060.52] Human. |
[1060.68 --> 1062.70] Another human that's not part of my family. |
[1062.84 --> 1063.48] Isn't that nice? |
[1064.24 --> 1065.76] They're sick of hearing about it, right? |
[1065.98 --> 1066.20] Yeah. |
[1067.12 --> 1067.44] Right. |
[1067.60 --> 1067.94] Okay. |
[1068.08 --> 1075.76] So if someone's listening to this and you are using Linkerd, and especially if it works |
[1075.76 --> 1080.46] and you don't think you need to get back to William and the Boyan team and the Linkerd |
[1080.46 --> 1082.10] community, that's actually wrong. |
[1082.10 --> 1084.72] Like, go and show a sign of gratitude. |
[1084.88 --> 1085.54] Say, hey, thank you. |
[1085.56 --> 1086.12] This is great. |
[1086.28 --> 1087.06] Share your use case. |
[1087.24 --> 1088.60] Share what you like about it. |
[1088.90 --> 1092.76] Even if everything is perfect, sharing that is worth it. |
[1092.92 --> 1094.28] People will appreciate it. |
[1094.34 --> 1095.24] And you've heard it from William. |
[1095.44 --> 1097.48] So do as William says. |
[1097.74 --> 1098.66] That's what I say. |
[1098.92 --> 1099.10] Yeah. |
