[2262.30 --> 2264.04] sometimes you just have SSH, |
[2264.26 --> 2265.00] you don't have |
[2265.00 --> 2265.78] a lot of options, |
[2265.78 --> 2266.78] and you need it |
[2266.78 --> 2267.48] to be there |
[2267.48 --> 2268.32] on the command line. |
[2268.52 --> 2269.64] And that's what |
[2269.64 --> 2270.64] Lazy Docker did for me. |
[2270.90 --> 2271.48] And the fact that |
[2271.48 --> 2271.92] I discovered |
[2271.92 --> 2272.92] one of my containers |
[2272.92 --> 2273.92] was having an issue |
[2273.92 --> 2275.16] was just kind of a bonus. |
[2275.70 --> 2276.88] And it's a great way |
[2276.88 --> 2278.76] to reconnect |
[2278.76 --> 2279.72] or I guess, |
[2279.82 --> 2279.98] what, |
[2280.06 --> 2281.30] reassociate yourself |
[2281.30 --> 2282.54] with what the hell's |
[2282.54 --> 2283.46] going on on a box |
[2283.46 --> 2284.52] if you haven't been |
[2284.52 --> 2285.30] on there in a little bit. |
[2285.82 --> 2286.88] I've got another one |
[2286.88 --> 2287.36] for you |
[2287.36 --> 2289.54] that is part of Docker, |
[2289.68 --> 2289.96] actually. |
[2290.70 --> 2292.14] Just log into a box |
[2292.14 --> 2292.48] that's running |
[2292.48 --> 2293.18] a few containers |
[2293.18 --> 2294.58] and type Docker stats. |
[2295.26 --> 2296.56] It is pretty much |
[2296.56 --> 2297.38] like htop |
[2297.38 --> 2298.20] or top, |
[2298.34 --> 2298.80] I suppose, |
[2299.04 --> 2300.58] for all of your containers. |
[2300.94 --> 2301.86] It will show you |
[2301.86 --> 2302.88] the name of the container, |
[2303.00 --> 2304.04] the CPU usage, |
[2304.56 --> 2305.20] the amount of memory |
[2305.20 --> 2306.22] that's being used, |
[2306.50 --> 2307.24] net IO, |
[2307.46 --> 2307.96] block IO, |
[2308.12 --> 2309.00] all that kind of stuff. |
[2309.10 --> 2309.72] And also, |
[2309.86 --> 2310.68] how many PIDs |
[2310.68 --> 2311.72] that particular container |
[2311.72 --> 2312.26] has created. |
[2312.26 --> 2312.62] So, |
[2313.12 --> 2313.70] I can see, |
[2313.82 --> 2314.18] for example, |
[2314.30 --> 2314.98] here that Plex |
[2314.98 --> 2317.08] needs 140 PIDs |
[2317.08 --> 2318.02] within that container. |
[2318.80 --> 2319.32] Whereas, |
[2319.64 --> 2320.54] say, |
[2320.64 --> 2321.08] something like |
[2321.08 --> 2321.92] a simple Nginx |
[2321.92 --> 2323.32] container is like seven. |
[2324.92 --> 2325.44] Yeah, |
[2325.58 --> 2325.74] oh, |
[2325.78 --> 2326.56] this is great. |
[2326.90 --> 2328.12] I'm looking right now. |
[2329.26 --> 2330.30] Oh my gosh. |
[2330.72 --> 2331.48] Some of these |
[2331.48 --> 2332.92] are such hogs. |
[2333.44 --> 2333.64] Yeah. |
[2333.68 --> 2334.40] It's shocking |
[2334.40 --> 2335.86] how bad some of these are. |
[2336.04 --> 2336.70] The Java apps |
[2336.70 --> 2337.14] in particular. |
[2337.28 --> 2337.36] So, |
[2337.50 --> 2338.84] the worst offender for me, |
[2338.90 --> 2340.02] I've got BookSonic running |
[2340.02 --> 2341.92] and I've actually used |
[2341.92 --> 2343.18] Docker Compose's spec |
[2343.18 --> 2344.66] to limit it to one gigabyte |
[2344.66 --> 2345.08] of RAM. |
[2345.24 --> 2345.40] So, |
[2345.90 --> 2346.98] for those of you that don't know, |
[2347.10 --> 2349.76] BookSonic is an audiobook-friendly |
[2349.76 --> 2350.76] version of the |
[2350.76 --> 2353.12] Subsonic Java-based server |
[2353.12 --> 2354.14] that is now |
[2354.14 --> 2355.64] like a decade old |
[2355.64 --> 2356.84] or more. |
[2357.24 --> 2357.90] And this thing, |
[2357.94 --> 2359.20] it runs like a pig. |
[2359.46 --> 2359.74] I mean, |
[2359.80 --> 2360.64] it's using |
[2360.64 --> 2362.46] 900 megs of RAM |
[2362.46 --> 2365.06] to just sit there |
[2365.06 --> 2365.92] and do nothing. |
[2365.92 --> 2367.56] I mean, |
[2368.24 --> 2370.44] you know what we need |
[2370.44 --> 2370.60] is, |
[2370.68 --> 2371.08] do you remember |
[2371.08 --> 2371.42] like, |
[2371.50 --> 2372.02] there was the, |
[2372.28 --> 2373.14] maybe you don't, |
[2373.18 --> 2373.58] this might have been |
