Thanks guys! Heads all mixed up because I used ansible for ‘python for entrepreneurs’, and then doing the crash course in docker, nginx, heroku... trying to mix everything together (there’s some overlap but not all, eg lets_encrypt is needed for docker?)... so just a bit confused and heads all over the place
And have a lot of free credits on Aws, so trying to figure out how to get elastic beanstalk working with docker etc....
When you're developing, it's much easier to not worry about https.
Right now I’m trying to figure out how to port the ansible code to docker lol
@michael, went through that chapter and docker. I’m trying to deploy a docker container to amazon ecs... I’m finding it much more challenging than expected... still trying to get it done.. is there an easy way to launch a docker container onto aws? I have a lot of free credits on aws
@rogerying AWS has super locked down linux machines. Try it on a local VM or install the local docker tools for windows or macOS and do it there first. That should help iron out what is giving you trouble at AWS. BTW, you are better off going with DigitalOcean or Linode. They also have credits but they charge about 12x (not percent, times!) less than EC2 for the same machine. Over time, that’d be worth it. You can use these links to get the credits there if you want….
Digital ocean: http://do.co/python
Linode: https://talkpython.fm/linode
Hi @_ChrisMay_twitter I feel like they are both so super close to simple just get into VMs and go that there really isn’t much of a difference. They each offer other features and maybe those matter to someone but I doubt it matters a lot. But EC2 is complex and pricy. What you get for $5 at either will cost you about $157 at AWS (bandwidth + compute price).
And thanks for the referral code! I haven't paid for my Linode yet, and it's been a few months. :D
@Michael, I’m really finding out how locked down AWS is the hard way!!! Am doing the docker container with pyramid and JUST got it working!! (Only took a week) my suggestion is that for future reference, to run uwsgi and nginx on a docker container use supervisor instead of systemd (which was in the 100webapps course), docker doesn’t like systemd for some reason.. or at least I couldn’t get it to work....

Hello All,
I need some pointers from you good people.
I have a certificate (PEM) file in text format and I want to extract information from it (for eg. Serial number, Issued to, Validity from and to).
I have tried using RegEx but prefer not to use. I have gone through the SSL and X509 documentation but still not able to get it.
Sample certificate:

Reason for not choosing regex: As I might be handling certificates from different vendor, the elements of the certificate might vary and cause the script to fail
Does anyone know why a flask app would run ok from the terminal using “python app.py” but the same app produces only 404’s when run with a vscode debugger launch configuration? I generated the configuration with the “add configuration" option and while it does seem to run it only produces log output like this: "127.0.0.1 - - [05/Jul/2019 12:01:49] "GET / HTTP/1.1" 404 -“
@MarkDHarris Yes, there is a big difference. If you have some kind of code in the ‘main’ section, i.e. if name == ‘main1, that will not be run in the -m flask run way.
Probably some sort of blueprints not getting registered or something, so the routes aren’t set, hence the 404.
Hi @dsod It was actually being attacked with a DDOS. I managed to changes some things and fight them off (detected what they were pounding on and just stopped responding to them, which freed up the site to work for you all again). They eventaully realized it wasn’t working and went away.
@rogerying MongoDB on an AWS cluster? Yeah, not bad. But you should explore MongoDB Atlas. It’s just that but they do all the tricky deploment, backup, upgrades, etc for you, on AWS. I would definitely use it if I were on AWS (I’m not :) ).
Stupid question: how do u pass a variable from pyramid controller to template and then to be used either react.js or Vue.js... would u just simple do a <script>let var1 = ${variable_from_controller}</script> and use var1 in Vue or react main code which may be a separate js file? What’s usually best practice for this?
@rogerying Yes, that’s exactly it. I just put a <script> tag at the top of the page, drop in the values into JS variables, then grab them in the scripts. For example, we round-trip your preferences for your video player on the courses this way. Whether you want closed-captions shown, etc.
<script>
var site = site || {}
site.player = site.player || {}
site.player_ctrl = site.player_ctrl || {}
var debug = debug || {}
debug.level = "${"dev" if view.dev_mode else "prod"}"
var api_data = {
'lecture': ${lecture.id},
'ready': true,
'next_lecture_url': '${next_lecture.play_url if next_lecture else ''}'
};
site.player_ctrl.preferences_state = {
captions: ${'true' if preferences.captions else 'false'},
quality: ${preferences.quality},
speed: ${preferences.speed},
ready: true,
sync_off: false
}
</script>
This is in the player chameleon file, notice this is a blend of JS and PYTHON. :) Here is the result on a page (for my settings).
<script>
var site = site || {}
site.player = site.player || {}
site.player_ctrl = site.player_ctrl || {}
var debug = debug || {}
debug.level = "prod"
var api_data = {
'lecture': 200501,
'ready': true,
'next_lecture_url': '/player/course/building-data-driven-web-applications-in-python-with-flask-sqlalchemy-and-bootstrap/lecture/200502'
};
site.player_ctrl.preferences_state = {
captions: false,
quality: 1,
speed: 1.0,
ready: true,
sync_off: false
}
</script>
Let's say I've built an simple employee list app. Name, email, date of hire are the only fields. Right now, I've built the front-end with jinja templates. If I wanted to instead use angular for the front end, do I use ajax calls to retrieve the data from
myapp.com/employee-list?
Hi @ryentzer Yes, that’s what I’m doing because I need a little server-side data to power the startup of the js app. There are still a handful of JSON-based APIs that the player calls as it does its job. So, for me, it’s a combo. Could also be a total plain JS launch then only APIs (as you’ve said) but I already have to render that page in Chameleon so might as well give the player the startup data while I have it. There is nothing private in there anyway.
