So, I'm trying to install Airflow on my laptop and I was able to do that using WSL but I can't seem to open it.
My webserver is running but I cant open it on localhost:8080
The system is taking eons to run airflow scheduler

I have installed apache airflow using docker desktop for windows and able to create DAGs and running webserver without issue. Here my question is, am unable to find airflow.cfg file in my local machine.
I am new to Airflow and docker please help me to find this one.
I am trying to get Airflow running on a local Docker Desktop for Mac installation using the Quick Start instructions for a Docker installation at https://airflow.apache.org/docs/apache-airflow/stable/start/docker.html. The install seems to go correctly, but when I start up the services using docker-compose up, all the services launch except for the webserver. That service starts, but then fails and restarts, over and over. The log shows this error:
EDIT: I found the issue in case someone else runs into it. The default configuration of Docker desktop for Mac doesn't allocate enough memory to run webserver. I bumped up the memory allocation in Docker, restarted everything, and all was good.
increasing the memory configuration of the docker worked for me
Edit:
Docs for docker configurations on mac: https://docs.docker.com/docker-for-mac/
My OS is Mac OS. I followed airflow official installation guide to install. But when I test: airflow test tutorial print_date 2015-06-01 from airflow testing it doesn't print any output. The result is here.. I wonder did I install it successfully? I've run other commands on the official airflow testing page. They report no error.
So far I see only WARNING output, it doesn't mean that airflow isn't running nor installed improperly. You'd have an easier time testing your install with airflow list_dags and you probably must run airflow initdb before most of the commands (and look at the airflow.cfg file).
I have an application that builds in 5 minutes on the Mac. When I try to build in Docker or directly in Ubuntu, the machine completely hangs at some point. It so bad that I can't even ssh into the machine. It eventually times out. I am using Meteor 1.4.2.3, Ubuntu 16.04 and Docker 16.04 with Meteor installed.
I thought maybe it was related to tar and 7z, so I upgraded tar and 7z. Still hangs. It hangs when I building on web.browser. There is high I/O waits and a bunch of blocked processes according to vmstat.
This is the command I'm running:
meteor build --allow-superuser --server-only --directory /tmp/build
Is their any way to get more info about what's going wrong? I also tried to
meteor remove ecmascript --allow-superuser
b/c one article said this may be an issue. Hangs.
I am trying to get my localhost working on my remote (mediatemple) server.
I have bundled it up and have a /myurl.com/bundle folder with the following files.
this folder contains
main.js
npm-debug.log
programs
server
How do I get this to run?
You should take a look in the README inside the bundle folder. Normally everything ist described there to start your app.
Make sure that NODEJS and MONGO is installed on your remote server. This is NOT included in your bundle as well as NODEJS is not present.
If you are running a system like debian or ubuntu normally you can do the installation with
apt-get install nodejs mongo
Make sure, that the nodejs has release v0.10.36 or v0.10.38
node --version
At the README you see the necessary ENV-VARS like MONGO_URL and PORT you need to set to start your meteor app.
If you have running a apache server already the PORT 80 is already blocked, so try PORT=3000 to start your meteor app.
Example:
MONGO_URL='mongodb://localhost:27017/yourapp' ROOT_URL="http://yourhost" PORT=3000 node main.js
If using as above you do not need to export the ENV-VARS before start
Sometime when starting, there are missing NPM – you get fiber errors
In that case
cd programs/server
npm install
and the try start again.
Good luck

(I'm writing this response assuming that you are not worried about scalability issue, respond in comment if you want to scale your app)
The best option for running a node application, which Meteor application is, is by using forever.
npm install forever
forever start simple-server.js
If you want to figure out how to see the log files and how to stop/restart your service, you can run forever --help to see all the commands.
