16:09 cdthompso1 use the youtube sprocket to improve video quality. it's great at 480p
16:10 Cata yeah 480 fixed, thanks!
16:10 Alhaj thanks
16:10 That joined #virtualJUG
16:10 sjmaple I wish there was a way of adding the default video quality in the embedded video on virtualjug.com but i'm not aware of any way

16:19 baunes joined #virtualJUG
16:20 yawz When I just joined Daniel was mentioning the containerization book. Did he say that we could get it for free?
16:20 sjmaple The Oreilly book?
16:20 yawz Yes
16:21 tjololo yawz: bit.ly/2jWDSF7
16:21 yawz Thank you! ;)
16:22 KJVJ joined #virtualJUG
16:23 nickolay This schema looks like a frankenstein
16:23 nickolay too much info :-)
16:24 grg joined #virtualJUG
16:25 cdthompso1 that sounds like religion getting in the way, centos in prod but ubuntu in QA
16:25 FaisalFeroz joined #virtualJUG
16:25 McK Debug through docker is not as easy
16:25 McK IT's easier to run the microservices directly
16:26 McK like StandaloneFoo class
16:26 H joined #virtualJUG
16:27 cdthompso1 this alone is every dev should be best friends with an ops guy
16:27 McK Just run the same JVM you are used to, no?
16:27 cdthompso1 ...why...
16:27 McK Why not?
16:28 LWG joined #virtualJUG
16:28 cdthompso1 sorry, was correcting my typo, not questioning JVM choice ;-)
16:29 cdthompso1 oh
16:29 cdthompso1 ugh
16:29 cdthompso1 cannot bundle oracle fully legally in base image. that's important
16:30 sjmaple I remember they released a statement about that, but can't remember what it said
16:30 sjmaple Bruno Borges put something out I think
16:30 cdthompso1 thnks. i'll google that
16:31 McK Why not one for prod?
16:31 sjmaple https://www.java.com/en/download/faq/distribution.xml
16:32 McK Why not start MySQL docker image?
16:34 sjmaple https://hub.docker.com/u/danielbryantuk/
16:35 MsL joined #virtualJUG
16:35 McK build metadata through the docker image name?
16:35 menchester5 joined #virtualJUG
16:35 McK concat?
16:35 cdthompso1 this implies oracle jdk on image is cool:  https://blogs.oracle.com/brunoborges/
16:35 LWG joined #virtualJUG
16:35 sjmaple I wouldn't do anything without legal advice :)
16:36 McK Where do you save this metadata on the container after it has been pushed?
16:37 cdthompso1 this point on latest is key. i've seen people make this mistake in svn. don't use 'latest" alias
16:37 McK I'm planted :)
16:37 sjmaple lol
16:38 sjmaple your question ironically slowed down the speed at which the answer would get to you :D
16:38 McK Dockerfile labels is too late.
16:38 McK you build, push
16:38 McK then run tests
16:38 McK right?
16:38 McK After test pass you should tag
16:39 McK what am I missing?
16:39 jimtyhurst left #virtualJUG
16:41 sjmaple does this bit answer your question McK?
16:41 McK No
16:41 shelajev :)
16:41 McK It's emphemawral
16:41 cdthompso1 i think that's his point here. label is temporal for runtime only
16:41 McK ephemeral
16:41 McK He said label QA Passed right
16:41 McK ?
16:41 McK Thus you should be able to label a pushed image
16:42 cdthompso1 ephemeral -- better word
16:42 Jawnnn joined #virtualJUG
16:42 cdthompso1 binary repo -- that's where my head was going
16:43 McK yes
16:43 shelajev it makes sense, you'd like to store your containers in an artifact repository anyway
16:43 shelajev so that's where you attach all the metadata
16:43 maryg joined #virtualJUG
16:44 kreeves joined #virtualJUG
16:44 madmas_ would be nicer if it can be attached to the ctual binary file, though, maybe something similar like JPEG EXIF data, so one could still get the context without referencing the repository
16:44 maryg joined #virtualJUG
16:44 mil joined #virtualJUG
16:45 McK If you use Jenkins, you can run the same stuff locally on your laptop
16:45 McK can't
16:45 LWMg joined #virtualJUG
16:46 McK This code means you can't run just run it in your local laptop
16:46 McK IT can only run in Jenkins
16:49 McK I think it's better to encode the code in Gradle or Maven, so you can do this on the latop with the same command
16:49 cdthompso1 off the wall question: can you invoke selenium in there?
16:49 MsL joined #virtualJUG
16:49 shelajev yeah, selenium - definitely
16:49 Charmin Can a doc container be a Jenkins slave directly ?
16:51 shelajev yeah, I think I'd rather bring the docker containers into my tests with something like testcontainers, rather than bring the tests run to a forest of the docker containers with a special plugins / syntaxes
16:52 McK So no need for the Docker Jenkins Plugin
16:53 McK to run the Docker Compose
16:55 McK Very good to know about the first bullet!
16:58 gge joined #virtualJUG
16:59 cdthompso1 what's the symptom of the entropy problem?
16:59 cdthompso1 oh, freeze. ugh
17:00 tahir joined #virtualJUG
17:00 sjmaple please add any final questions now
17:01 McK What's your take of mocking vs using the real stuff using Docker like MySQL, Consul, etc?
17:01 rmarcu why we nedd to use docker hub or a private hub and not to use save image and use it where we want to build
17:02 millross_ joined #virtualJUG
17:03 McK Good lecture
17:03 cdthompso1 good call. also call out to strangler pattern
17:03 cdthompso1 yes, this was great
17:04 elfcan joined #virtualJUG
17:04 jyeary Thank you for a nice presentation.
17:05 McK Why avoid spinning up MySQL?
17:05 Alhaj Thank you
17:06 McK Implement data as part of your unit test
17:06 McK Insert data
17:06 Alexandra Thank you!
17:07 cdthompso1 nginx delivered that book to me via email while we were talking
17:07 cdthompso1 looking forward to the takeaway
17:08 McK https://github.com/testcontainers/testcontainers-java
17:08 McK Highly recommend it
17:08 tjololo Thank you very much:)
17:08 shelajev +1 for the testcontainers!
17:08 shelajev +1 for the artifactory!
17:09 McK Only if they improved their Docker version of Artifactory :)
17:09 McK Tn
17:09 McK Tnx
17:12 tjololo really usefull stuff both on youtube and here on irc!

22:25 sjmaple glad you thought so tjololo - is this your first vJUG session or have you been to previous presentations?
22:27 * pdurbin keeps meaning to go back and watch the presentations
22:30 pdurbin sjmaple: did I ever tell you that what I'd love is an audio version of the presentations? A podcast, basically.
22:31 sjmaple pdurbin: do you think they would work for sessions that would require visuals?
22:31 sjmaple it's easy to do :)
22:31 sjmaple but would they work? or would they be frustrating?
22:31 pdurbin usually it's just talking heads :)
22:32 sjmaple depends on the session - sometimes it can be demo, imagine Josh Long
22:32 sjmaple sometimes, talking over pictorial slides
22:32 pdurbin sure, but a high percentage would work well enough as audio, I think
22:32 pdurbin could reach more people
22:32 sjmaple when it's just words on a slide, it's fine as they're just talked over - theres nothing to describe
22:32 sjmaple we can definitely try it to see
22:32 sjmaple in fact
22:33 sjmaple we could do the last 5 sessions as a test :)
22:33 pdurbin sure, sounds great
22:33 sjmaple and you could be our guinea pig :)
22:33 pdurbin just tell me the RSS feed URL :)
22:34 sjmaple so, I'm in Tartu, Estonia now, on pretty crappy internet at 1:30AM in the morning doing slides for 2 sessions tomorrow - there are definitely better times to do this - let me give it a go next week :)
22:34 pdurbin heh, ok, no rush
22:34 sjmaple this is where our podcast is https://soundcloud.com/vJUG
22:34 sjmaple it's been inactive for a number of months, but I have a plan to kick it back into action :)
22:34 pdurbin right, I'm already subscribed to that one
22:34 sjmaple this will help it become active in fact :)
22:35 pdurbin fantastic
22:36 pdurbin I'm glad I spoke up. :)
22:36 sjmaple totally - it's a community that everyone owns, so we completely value, appreciate and respect all views and opinions
22:37 sjmaple in fact, I still need to send out a survey to get more info from our community to understand what they want/expect from our group!
22:37 pdurbin oh, I didn't know I'm a part owner ;)
22:37 sjmaple it's easy to guess, but harder to get it right!
22:38 sjmaple you totally are! Communities are owned my members, not leaders. They just put the hours in :D
22:38 pdurbin in practice, if I'm really enjoying an episode as audio but I'm thinking "I would get so much more out of this with the visuals" then I could always switch to the video
22:38 sjmaple if it weren't for members, we'd just be talking to walls ;)
22:39 pdurbin At least I host the IRC logs. That's my small contribution. Even if I don't tend to watch the presentations. I watched the first 10 or so, I think.
22:39 sjmaple maybe I should record a 20 second intro saying similar. This is the audio version of a video on virtualjug.com. For the video, be sure to check out the website, but you can also enjoy this audio recording...
22:39 sjmaple they're really useful! thank you!
22:39 pdurbin Oh sure
22:39 * pdurbin give philbot a treat
22:40 pdurbin gives*
22:40 sjmaple lol
22:40 pdurbin is a fork of ilbot and my first name is Phil
22:41 pdurbin yeah, the 20 second intro would be a nice addition
22:41 pdurbin set expectations
22:41 pdurbin ymmv ;)
22:42 sjmaple hehm nice :)
22:42 pdurbin anyway, these potstickers are done. time to feed the kids. take care
22:42 sjmaple where are you based?
22:43 pdurbin Boston
22:43 sjmaple oh wow! I go there all the time!
22:43 sjmaple I'll ping you next time I'm in town and we'll grab coffee!
22:44 pdurbin absolutely. I work at Harvard if you're ever in Cambridge
22:44 pdurbin I meant to track you down at JavaOne a couple years back but I missed your session.
22:45 sjmaple cool! Our office is on Boyleston, but I can of course grab the train :)
22:45 sjmaple 399
22:46 pdurbin ah, I used to work at Berklee College of Music on Bolyston
22:46 sjmaple oh wow!, small world! :)
22:46 sjmaple But anyway, feed those kids ;o) Speak to you again soon! Remind me next week if I don't do those audio tracks
22:46 pdurbin heh, will do
22:46 * pdurbin rings the dinner bell
22:53 sjmaple :D
