QUESTION
Trying a simple python flask web app in docker 20.10.2, build 2291f61.
Doing the: docker build -t hello-world .
starts out ok (please see below), but ends with:
ANSWER
Answered 2021-Feb-27 at 01:41You should change the RUN
lines in the Dockerfile with apt-get
in them to use the -y
flag to skip asking you to confirm "yes".
The Dockerfile in the tutorial actually seems out of date or has errors in it. You need to use pip3
now to install Flask
and also include the -y
flag in your apt-get
commands. I edited the Dockerfile from the tutorial and posted below:
QUESTION
I am using Celery to asynchronously perform a group of operations. There are a lot of these operations and each may take a long time, so rather than send the results back in the return value of the Celery worker function, I'd like to send them back one at a time as custom state updates. That way the caller can implement a progress bar with a change state callback, and the return value of the worker function can be of constant size rather than linear in the number of operations.
Here is a simple example in which I use the Celery worker function add_pairs_of_numbers
to add a list of pairs of numbers, sending back a custom status update for every added pair.
ANSWER
Answered 2020-Jan-05 at 17:48It's a pattern that is not supported by celery although you can (somewhat) trick it out by posting custom state updates to your task as described here.
Use update_state() to update a task’s state:.

QUESTION
One of the issues is I’m running into is getting additional data from a command in slack. I️ don’t want to use Slash commands because I️ can’t expose my localhost to the world.
Example:
...ANSWER
Answered 2017-Nov-13 at 13:08How to get "additional information"
You will get the complete input string in the text property, e.g. "do 2"
. All you need to do is split the string into words. I am not a Python developer, but apparently split() will do the job.
Exposing your localhost
I would strongly recommend to go ahead and expose your localhost with a VPN tunnel. It makes development so much easier. You can use ngrok to securely expose your localhost to Slack.
"Dont want to use slash commands"
You will always need an app (e.g. Python script) on an exposed host for any custom functionality to work with Slack. Actually, slash commands are easier to implement then Event API and RTM, so I would recommend it for your case.
