I have installed a local instance of Readthedocs server, but anytime I try to build a github repository the app gets stuck in the Triggered state!.
There is no errors or exceptions, just regular info messages:
[25/Apr/2017 14:21:11] INFO [readthedocs.projects.utils:81] Running: 'ln -nsf /var/www/my-project/user_builds/test1/rtd-builds/latest /var/www/my-project/public_web_root/test1/en/latest' [/var/www/my-project]
[25/Apr/2017 14:21:11] INFO [readthedocs.projects.tasks:844] (Build) [test1:] Updating static metadata
Any idea what could be causing this issue?
so I had this problem, and there seems to be a lot of different things that could cause it, because I've seen various postings about it on different forums however none of the solutions posted helped me. The only posting i have book marked is this github issue.
for me I found that the documentation would build if I ran the command python manage.py runserver 0.0.0.0:8000, but would be stuck in a triggered state if I used my computers ip address; the solution was to use the above command but to add the following to readthedocs/settings/local_settings.py :
import os
# Set this to the root domain where this RTD installation will be running
PRODUCTION_DOMAIN = os.getenv('RTD_PRODUCTION_DOMAIN', '10.x.x.x:8000')
# Enable private Git doc repositories
ALLOW_PRIVATE_REPOS = True
best of luck.

After quite a bit of trial and error and a step by step attempt to find solutions I thought I share the problems here and answer them myself according to what I've found. There is not too much documentation on this anywhere except small bits and pieces and this will hopefully help others in the future.
Please note that this is specific to Django, Celery, Redis and the Digital Ocean App Platform.
This is mostly about the below errors and further resulting implications:
OSError: [Errno 38] Function not implemented
and
Cannot connect to redis://......
The first error happens when you try run the celery command celery -A your_app worker --beat -l info
or similar on the App Platform. It appears that this is currently not supported on digital ocean. The second error occurs when you make a number of potential mistakes.
PART 1:
While Digital Ocean might remedy this in the future here is an approach that will offer a workaround. The problem is the not supported execution pool. Google "celery execution pools" if you want to know more and how they work. The default one is prefork. But what you need is either gevent or eventlet. I went with the former for my purposes.
Whichever you pick you will have to install it as it doesn't come with celery by default. In my case it was: pip install gevent (and don't forget adding it to your requirements as well).
Once you have that you can re-run the celery command but note that gevent and beat are not supported within a single command (will result in an error). Instead do the following:
celery -A your_app worker --pool=gevent -l info
and then separately (if you want to run beat that is) in another terminal/console
celery -A your_app beat -l info
In the first line you can also specify the concurrency like so: --concurrency=100. This is not required but useful. Read up on it what it does as that goes beyond the solution here.
PART 2:
In my specific case I've tested the above locally (development) first to make sure they work. The next issue was getting this into production. I use Redis as the db/broker.
In my specific setup I have most of my celery configuration in the_main_app/celery/__init__.py file but sometimes people put it directly into the_main_app/celery.py. Whichever it is you do make sure that the REDIS_URL is set correctly. For development it usually looks something like this:
YOUR_VAR_NAME = os.environ.get('REDIS_URL', 'redis://localhost:6379') where YOUR_VAR_NAME is then set to the broker with everything as below:
YOUR_VAR_NAME = os.environ.get('REDIS_URL', 'redis://localhost:6379')
app = Celery('the_main_app')
app.conf.broker_url = YOUR_VAR_NAME
The remaining settings are all documented on the "celery first steps with django" help page but are not relevant for what I am showing here.
PART 3:
When you setup your Redis Database on the App Platform (which is very simple) you will see the connection details as 'public network' and 'VPC network'.
The celery documentation says to use the following URL format for production: redis://:password#hostname:port/db_number. This didn't work. If you are not using a yaml file then you can simply copy paste the entire connection string (select from the dropdown!) from the Redis DB connection details and then setup an App-Level environment variable in your Digital Ocean project named REDIS_URL and paste in that entire string (and also encrypt it!).
The string should look like something like this (redis with 2 s!)
rediss://USER:PASS#URL.db.ondigitialocean.com:PORT.
You are almost done. The last step is to setup the workers. It was fine for me to run the PART 1 commands as console commands on the App Platform to test them but eventually I've setup a small worker (+ Add Component) for each line pasted them into the Run Command.
That is basically the process step by step. Good luck!
When working with a ColdFusion server you can access the CFIDE/administrator to set config values, which update the cfusion/lib/ xml files (e.g. neo-runtime.xml, neo-mail.xml, etc.)
I'd like to automate a deployment process that includes setting these administrator values so that I don't have to log in and manually set them for each new box that shares settings. I'm unsure of the best way to go about it.
Some thoughts I had are:
Replacing the full files with ones containing my custom settings. I've done this for local development, but it may not be an ideal method due to CF hot-fixes potentially adding/removing/changing attributes.
A script to read the wddx xml file and replace the attribute values. I'm having trouble finding information about how to do this method.
Has anyone done anything like this before? Or does anyone have any recommendations on how to best go about this?
At one company, we checked all the neo-*.xml files into source control, with a set for each environment Devs only had access to the dev settings and we could deploy a local development environment with all the correct settings for new employees quickly.
but it may not be an ideal method due to CF hot-fixes potentially adding/removing/changing attributes.
You have to keep up with those changes and migrate each environment appropriately.
While I was there, we upgraded from 8 to 9, 9 to 11 and from 11 to 2016. Environments would have to be mixed as it took time to verify the applications worked with each new version of CF. Each server got their correct XML files for that environment and scripts would copy updates as needed. We had something like 55 servers in production running 8 instances each, so this scaled well.
There is a very usefull tool developed by Ortus Solutions for this kind of automatizations called cfconfig that can be installed with their commandbox command line utility. This tool isn't only capable of setting configurations of the administrator: It is also capable of exporting/importing settings to a json file (cfconfig.json). It might be what you need.
Here is the link to their docs
https://cfconfig.ortusbooks.com/introduction/getting-started-guide
CFConfig worked perfectly for my needs. I marked #AndreasRu answer as accepted for introducing me to that tool! I'm just adding this response with some additional detail for posterity.
Install CommandBox as part of deployment script
Install CFConfig as part of deployment script
Use CFConfig to export a config.json file from an existing box that will share settings with the new deployment. Store this json file in source control for each type/env of box.
Use CFConfig to import the config.json as part of deployment script
Here's a simple example of what this looks like on debian
# Installs CommandBox
curl -fsSl https://downloads.ortussolutions.com/debs/gpg | apt-key add -
echo "deb https://downloads.ortussolutions.com/debs/noarch /" | tee -a /etc/apt/sources.list.d/commandbox.list
apt-get update && apt-get install apt-transport-https commandbox
# Installs CFConfig module
box install commandbox-cfconfig
# Import config settings
box cfconfig import from=/<path-to-config>/config.json to=/opt/ColdFusion/cfusion/ toFormat=adobe#11.0.19
I have deployed two rails apps to Digital Ocean, Ubuntu 18.04 with Passenger and Nginx.
Both apps were built on rails 5.2.2 with ruby 2.5.1, and the second app has all the same gems at the same versions. While the first app runs fine, the second will not launch.
The last useful line of the Passenger log says:
[ E 2020-08-06 22:41:56.6186 30885/T1i age/Cor/App/Implementation.cpp:221 ]: Could not spawn process for application /var/www/html/AppName_Prod/current: The application encountered the following error: ActiveSupport::MessageEncryptor::InvalidMessage (ActiveSupport::MessageEncryptor::InvalidMessage)
I know this is somethign to do with the master.key file, but that is present and contains the correct key. I'm not using environment vars to store the master keys - they are in the master.key file inside each app's dir structure.
I've read every SO post I could find on this and none have solved my issue.
Any suggestions for getting these two apps (and more) to work on the same droplet?
I'm all out of ideas.
Thank you for any help you can offer.
For anyone who might have the same issue, it was a bit deceptive.
I had tried rails credentials:edit and it didn't fix the issue, but I found that the app's containing folder was owned by user:user, whereas my other app was owned by user:root.
When I changed this, everything started to work.
I hope it helps someone because I didn't find this info anywhere online and it was a lot of trial and error.
Use ls -l to list the current owner of folders in the current working directory, so you can compare them.
For me, this turned out to be somewhat complicated. I had provisioned my server using Ansible, which has a task to copy the Nginx conf. After provisioning the server, I changed RAILS_MASTER_KEY.
It turns out that my Ansible task does not re-write the Nginx conf if it already exists on the server (the file is not compared, I guess). So although I updated RAILS_MASTER_KEY in my Ansible playbook (and it was even getting copied across to the server's environment variables!), it was not accessible to Rails through passenger because it does not pass on the user's environment variables.
Whew!
To fix this (and create a snowflake server in the process...) I manually logged into the server and updated RAILS_MASTER_KEY to my new value in the Nginx passenger_env_var.
Please help I have trouble with Divio App trying to making it work.
When I press "set up project"
it gives me this
*
Creating workspace
cloning project repository
Cloning into '/c/Users/Ubisoft/Documents/iloveit'...
Bad owner or permissions on /home/divio/.ssh/config
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
There was an error trying to run a command. This is most likely
not an issue with divio-cli, but the called program itself.
Try checking the output of the command above.
The command was:
git clone git#git.divio.com:iloveit.git /c/Users/Ubisoft/Documents/iloveit

and in windows power shell it gives me this

I also tried this from virtual MacOS and getting this message:
https://i.stack.imgur.com/QccvY.png
I also tried to mess arouond with creating SSH keys but didn't work out.
Can someone provide me step by step explanation how to make this wonderful app work?
In the Windows examples you show, I see:
Bad owner or permissions on /home/divio/.ssh/config
I am not sure how that has happened, but that is what is preventing your local environment from providing the expected key to the Divio Control Panel.
In the Macintosh example, the environment doesn't have a key that the Control Panel knows about.
You will need to add the key (probably from ~/.ssh/rsa_id.pub) to https://control.divio.com/account/ssh-keys/. If you don't already have a key in the Macintosh environment, you will need to set one up.
For anyone who may face this issue. On my MacOS virtual machine I managed to find solution. Looks like it is Internet Service Provider blocking port 22 something like that. Okay looks like problem resolved. I used VPN and without any hastle with SSH I got different result. Looks like it is working now not finished creating project yet but promising:

We've been using appcfg.py request_logs to download GAE logs, every once in a while it throws the error:
httplib2.SSLHandshakeError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:661)
But after a few times trying it works out, sometimes also it works after updating gcloud using gcloud components update. We thought it might be some network throttling issue of some kind and didn't give it enough thought. Lately though, we're trying to figure out what is causing this.
The full command we use is:
appcfg.py request_logs -A testapp --version=20180321t073239 --severity=0 all_logs.log --append --no_cookies
It seems the error is related to httplib2 library, but since it is part of the appcfg.py calls we're not sure we should tamper with something within its calls
Versions:
Python 2.7.13
Google Cloud SDK 196.0.0
app-engine-python 1.9.67
This has become more persistent now and I couldn't download logs for a few days now no matter how many times I try.
Looking at the download logs command I tried the same command again but without the --no_cookies flag to see what would happen.
appcfg.py request_logs -A testapp --version=20180321t073239 --severity=0 all_logs.log --append
I got the error:
Error 403: --- begin server output ---
You do not have permission to modify this app (app_id=u'e~testapp').
--- end server output ---
Which lead me to the answer provided here https://stackoverflow.com/a/34694577/1394228 by #ninjahoahong. This worked for me and logs where downloaded from first trial in case someone faces the same issue
There's also this Google Group post which I didn't try but seems like it does the same thing.
Not sure if removing the file ~/.appcfg_oauth2_tokens would have other effects, yet to find out.
Update:
I also found out that my httplib2 located at /Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/httplib2 was version = "0.7.5", I upgraded it to version = '0.11.3' using target location(directory) upgrade command:
sudo pip2 install --upgrade httplib2 -t /Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/httplib2/
