[2261.84 --> 2266.48] But if you take these principles into the workplace, I guarantee you it's going to make you more |
[2266.48 --> 2272.16] employable, you'll earn a bigger salary. But as a team, it just makes your life so much easier, |
[2272.16 --> 2277.34] because you're not like, who's done this to the load balancer? Alex, was it you? No, it's in Git. |
[2277.40 --> 2280.42] You can go and look at GitBlaim and you know that it was Tim that broke the load balancer, |
[2280.42 --> 2286.08] not Alex this week. Yeah, don't let him. Yeah. And it's nice because, you know, |
[2286.14 --> 2291.48] places I've worked at, sometimes developers have full access to Kubernetes, which is fine. That's |
[2291.48 --> 2297.36] a choice made by the company. But anyone can then go kubectl apply or kubectl delete everything, |
[2297.36 --> 2302.36] and then it's gone. You know, and so GitOps basically says no more of that. We're separating |
[2302.36 --> 2306.50] our concerns. You know, if you want to get things into Kubernetes, you do it through Git, |
[2306.50 --> 2311.52] and then you use, you know, a controller or service to apply those to Kubernetes. So it's, |
[2311.88 --> 2315.76] it's very interesting. It's very, it's very bleeding edge. And a couple of places are doing |
[2315.76 --> 2320.72] this now for a couple, you know, Flux is one, Argo CD is another. And I'm sure there's a handful |
[2320.72 --> 2325.20] of others that are coming up. Even GitLab themselves does it. Portainer does it for Docker. I mean, |
[2325.50 --> 2329.94] this is a hot topic, but it's, it's really awesome. But at the end of the day, now as a developer, |
[2329.94 --> 2334.98] I'm like, okay, I can't, I can't make changes to Kubernetes directly, which I'm fine with. I'm fine with |
[2334.98 --> 2342.04] process. It has upsides and downsides. The upside is like you say, everything is declarative and it |
[2342.04 --> 2348.08] makes rebuilding stuff really, really easy. The downside is you have to make every single change |
[2348.08 --> 2354.42] that way, no matter if it's a one character change to a config file and whatever your peer review |
[2354.42 --> 2358.96] process is, you know, in a home lab, it's likely to be you going, yes, yes, mash, mash, mash. Yes, |
[2359.02 --> 2363.38] yes, yes. Whereas at work, you know, you might have to get your team lead to approve it and, |
[2363.38 --> 2367.62] you know, explain why you miss the semicolon off the end of a line or whatever it might be, |
[2368.14 --> 2372.54] you know, that kind of thing. So it has its upsides and downsides. I think for me, |
[2372.58 --> 2376.68] the upsides do outweigh the downsides simply because of everything we've talked about. |
[2377.44 --> 2383.24] Yeah, I agree. I agree. My, my notes section that I used to have on how to reconfigure my |
[2383.24 --> 2391.10] Kubernetes cluster in the case of an event is gone. It used to be a long list of helm commands that I |
[2391.10 --> 2397.60] used to run kube control, you know, commands that I run along with manifest manifest. And now that's |
[2397.60 --> 2403.10] just gone. It's just no, my, my documentation is the code. And I, I hate it when people say that, |
[2403.16 --> 2407.00] but it's true. Now, now my code is the documentation and documentation is the code. There's, |
[2407.12 --> 2411.38] there's no other way to do it. Well, it's the source of truth. It's the most up-to-date version |
[2411.38 --> 2417.12] of what's in production. I mean, the only other more truthful source would be actually production, |
[2417.12 --> 2421.30] but if you've been doing it all through GitOps anyway, they should be the same. |
[2421.68 --> 2426.76] That's right. Yeah. Yeah. It's a, it's pretty strict principle, but I, I, I enjoy it. You know, |
[2426.84 --> 2430.72] Argo CD is another one that I I've been wanting to play with. It's, it's pretty cool. It's, |
[2430.80 --> 2435.34] it's a lot more visual, you know, even before I was doing give up GitOps, I would still deploy |
[2435.34 --> 2441.74] stuff through Kubernetes. I had still use CI CD, you know, pipelines, commit manifests, |
[2441.74 --> 2446.92] and then have, you know, a kube control apply during CI. This is a little bit different and it's, |
[2446.92 --> 2449.32] it's pretty awesome. Pretty awesome. It's fun to explore. |
[2452.56 --> 2458.14] Talescale.com slash self-hosted. Go there to get a free personal account for up to 20 devices and |
[2458.14 --> 2463.20] support the show. Talescale is one of my absolute favorite discoveries of the last 12 months. It's |
[2463.20 --> 2469.18] a zero config VPN. You can install it on any device in minutes and manage the firewall rules for you. |
[2469.18 --> 2474.08] And it works from anywhere. I've been able to close all the ports in my firewall, thanks to the |
[2474.08 --> 2478.84] outbound nap punching that Talescale does. And this means that no matter where I am in the world, |
[2478.94 --> 2485.58] I can connect to my LAN as if I'm sat in this chair. And it is so great. I can hardly explain |
[2485.58 --> 2492.20] to you guys. I can also, thanks to their amazing subnet router technology, connect to the Synology |
[2492.20 --> 2496.54] box running at my mom's house or the server I have running at my dad's house as if I'm on their |
[2496.54 --> 2502.38] LANs as well. For me, one of the best parts is every device on my network gets a stable IP and |
[2502.38 --> 2508.06] auto-assigned domain that stays consistent no matter what network the device is on. Devices |
[2508.06 --> 2512.08] only connect after signing in through your existing identity provider. This means you |
[2512.08 --> 2517.24] can more easily enforce multi-factor authentication and deauthorize those who you've shared things |
[2517.24 --> 2522.38] with who you perhaps wish you hadn't. You can try it for yourself for free for up to 20 machines |
[2522.38 --> 2528.78] at talescale.com slash self-hosted. And just imagine, what if this is how the internet worked? |
[2528.78 --> 2535.46] What if every machine had a static IP and a DNS name? And that address migrated around the world |
[2535.46 --> 2540.94] with you? And it was always encrypted? And you never had to worry about certificates? And all of |
[2540.94 --> 2546.12] this just happened automatically? That's Talescale. So go and try it out for yourself for free for up |
[2546.12 --> 2549.46] to 20 machines at talescale.com slash self-hosted. |
[2549.46 --> 2557.04] Jerry writes in, hey guys, in response to the Wi-Fi enabled e-ink device mentioned in episode 72, |
[2557.20 --> 2563.10] I thought you should check out pine64.org slash pine note. Hey, Jerry, I just want to say thanks |
[2563.10 --> 2567.00] for writing in with this one. I mean, I know the conclusion that Chris and I came to in the last |
[2567.00 --> 2572.10] episode was that for the most part, wherever you're going to want an e-ink display, there's going to be |
[2572.10 --> 2579.34] power and therefore a cheap tablet might make more sense. But if you really, really do want an e-ink |
[2579.34 --> 2585.98] display, you can go ahead and look at this pine note developer edition. It is $400. So what we were |
[2585.98 --> 2591.84] saying about e-ink displays being expensive definitely holds true with this device, but it does look cool. |
[2591.94 --> 2597.96] And obviously, you know, supporting the pine project is a noble endeavor. Those guys do great work over |
[2597.96 --> 2602.60] there. So you can go ahead and take a look at the link in the show notes to the pine note. |
[2603.86 --> 2608.24] And Joshua also writes in, I've been running Linux since high school and I've been self-hosting |
[2608.24 --> 2613.46] almost as long. I am currently getting my master's in cybersecurity engineering and I've been using the |
[2613.46 --> 2619.54] skills I learned to try and make my systems more secure. One tool I learned about recently is Linus. |
[2619.88 --> 2626.12] I think that's how you say it anyway. L-Y-N-I-S. This scans your configs and gives you suggestions to |
[2626.12 --> 2631.64] improve your security. Do either of you run any tools to help ensure you aren't making any obvious |
[2631.64 --> 2637.00] security mistakes? Now, Tim, I know that you do some stuff like this in your day job. I wondered if |
[2637.00 --> 2642.26] you had any suggestions for Josh. Yeah, great question. I was actually working on this today. |
[2642.54 --> 2647.76] There are a lot of tools you can use to do analysis on the things you use. For example, |
[2648.32 --> 2654.84] I was setting up container image scanning today to scan Docker containers to look for vulnerabilities, |
[2654.84 --> 2662.14] known vulnerabilities that are higher critical and if they were addressed or not. So there are lots of |
[2662.14 --> 2667.14] things you can do like that. You can scan them either at rest in a container registry or you can |
[2667.14 --> 2672.76] scan them even during runtime if they're in Kubernetes. And then if you are writing code, there's a lot of |
[2672.76 --> 2679.22] static code analysis tools you can use too as well to scan and look for vulnerabilities in either your |
[2679.22 --> 2685.40] code or dependencies that you're using for your code. Trivia is one that I was using today to set |
[2685.40 --> 2691.34] up and it's really, really awesome. And it's open source and they do a lot of scanning of a lot of |
[2691.34 --> 2696.98] different types. They're kind of an all-in-one now where they can scan code, dependencies, and containers. |
[2697.52 --> 2700.64] So now when we see a video come out from you in a few weeks' time on that, I'll be like, |
[2700.64 --> 2706.54] hey, you heard it here first. You know, I think for me, cybersecurity is one of those things. Like |
[2706.54 --> 2712.50] it's obviously a buzzword in certain areas, but just not being the tallest nail is the name of |
[2712.50 --> 2717.44] the game. Don't do silly things like open ports in your firewall you don't absolutely need. I mean, |
[2717.54 --> 2722.88] for me, since discovering Tailscale, I've actually been able to close every single port in my firewall. |
[2723.06 --> 2726.66] Like I don't have anything open anymore, not even WireGuard like I used to, |
[2726.66 --> 2731.72] because Tailscale does all the outbound nat punching that I need to get past my own firewall |
[2731.72 --> 2737.00] so I can connect to my LAN as if I'm, you know, here wherever I am in the world, which is just |
[2737.00 --> 2741.70] great. So stuff like that, you know, don't open ports in your firewall, I think is a super basic |
[2741.70 --> 2747.66] but really important principle. There's also stuff like using SSH keys or certificates if you want to, |
[2747.80 --> 2753.12] using TLS to make sure it is actually your website that you're connected to through Let's Encrypt. |
[2753.12 --> 2758.18] There's really no excuse these days not to. But I think beyond that, just don't be the tallest nail. |
[2758.34 --> 2764.88] Don't use a silly, stupid password like password123. At least make some basic effort. That kind of thing. |
[2764.94 --> 2768.34] Use a password manager, that kind of stuff. I think that's all you need to do, really. |
[2769.40 --> 2770.50] So Jackin writes, |
[2770.50 --> 2785.18] Jackin, I almost shed a tear on the last episode of Lass. I've got to be honest with you. I know Chris isn't here, |
[2785.60 --> 2789.08] but I was a huge fanboy of JB for many years before starting this show. |
[2789.74 --> 2794.06] And I owe a lot of what I can say and talk to about Linux, I think, to JB as a whole. |
[2794.06 --> 2797.98] So I feel you there, man. I feel you there. Now, he continues, |
[2798.28 --> 2802.74] on episode 71, a listener asked about thoughts on alternatives to the Raspberry Pi. |
