python - Connect to redis from another container in docker -

-

i have app, used tornado , tornado-redis. [image "app" in docker images] start redis:

docker run --name some-redis -d redis

then want link app redis:

docker run --name some-app --link some-redis:redis app

and have error:

traceback (most recent call last):   file "./app.py", line 41, in <module>     c.connect()   file "/usr/local/lib/python3.4/site-packages/tornadoredis/client.py", line 333 , in connect     self.connection.connect()   file "/usr/local/lib/python3.4/site-packages/tornadoredis/connection.py", line  79, in connect     raise connectionerror(str(e)) tornadoredis.exceptions.connectionerror: [errno 111] connection refused

i have tested code local tornado , redis, , works. problem in 

c = tornadoredis.client() c.connect()

why app cant connet redis-container? how fix that? use standart port 6379.

thanks!

tornadoredis attempts use redis on localhost. (see source here)

so need inform tornadoredis redis running (since docker image not running on localhost).

for example:

c = tornadoredis.client(host="<hostname>") c.connect()

in specific case, substitute "redis" "<hostname>".

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...
