KeyError: 'SECRET_KEY‘

[IceRain00]

when I nitialize Promgen using Docker: docker run --rm -it -v ~/.config/promgen:/etc/promgen/ line/promgen bootstrap，has the problem as follows:

Traceback (most recent call last):
  File "/usr/local/lib/python3.6/site-packages/environ/environ.py", line 273, in get_value
    value = self.ENVIRON[var]
  File "/usr/local/lib/python3.6/os.py", line 669, in __getitem__
    raise KeyError(key) from None
KeyError: 'SECRET_KEY'

During handling of the above exception, another exception occurred:

So what should I do to deal this problem 

[IceRain00]

Can anyone provide a detailed installation steps?

[kfdm]

Last week was a holiday in Japan. I will try to triage this today

[kfdm]

Some of the bootstrap handling should be fixed in #270
Let me try to tag a new release this week.

[kfdm]

I just released a new version of Promgen ( https://github.com/line/promgen/releases/tag/v0.47 ) can you give that a try and see if it works ?

[IceRain00]

I build the docker image by the release code 0.47，then I do as README "Initialize Promgen"
docker run --rm -it -v ~/.config/promgen:/etc/promgen/ promgen:0.47 bootstrap.
The problem above did not appear,but has the problem as following:

This maybe the problem of mysql config,but I set the config in docker-compose.yml as:

Database example: mysql://username:password@hostname/databasename

So can you provide a detailed dependency and installation description

[kfdm]

I'm sorry, can you try with https://github.com/line/promgen/releases/tag/v0.47.1 (there was a bug around some database checks in 0.47)

[IceRain00]

Still has a problem when I run :
docker run --rm -it -v ~/.config/promgen:/etc/promgen/ promgen:0.47.1 bootstrap

[kfdm]

It looks like the container is unable to write to /etc/promgen/promgen.yml can you check the permissions there ?

[IceRain00]

But I am the root user used on my developing machine，the core version of my machine is :

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=16.04
DISTRIB_CODENAME=xenial
DISTRIB_DESCRIPTION="Ubuntu 16.04.6 LTS"

[kfdm]

Perhaps you can try running with -u to change the user

-u, --user string Username or UID (format: <name|uid>[:<group|gid>])

Promgen is set to run as a non-root user (I think the uid defaults to 1000) but you can change it to a user on your local machine.

The error is showing that it can not write to ~/.config/promgen (which is mapped to /etc/promgen/ inside the container)
