postgresql - How to setup docker architecture -

-

i'd have following configuration:

               docker containers     ||||||||||||      ||||||||||||      |||||||||||| |          |      |          |      |          | |          |      |          |      |          | |          | <--> |          | <--> |          | |          |      |          |      |          | |          |      |          |      |          | ||||||||||||      ||||||||||||      ||||||||||||    nginx           web server         postgres

with following setup:

  1. nginx

    • change nginx.conf
    • add appropriate sites-available entry
    • link config sites-enabled

  2. postgresql

    • setup user login , password

  3. web server

    • clone repository
    • build release version
    • run server process

i have couple of questions well:

a) how pass secrets docker api keys, passwords , on?

b) possible clone repo docker or there other way that?

c) how , deploy such applications?

d) setup possible?

this setup common docker. i'd recommend using docker-compose (example) because makes setting drastically easier.

passing in secrets done through environment variables @ docker run time. if have many can store them in env-file.

yes, can clone repo docker container or during docker build. cloning private repo during docker build not feasible (without exposing credentials) it's recommended clone repo before running docker build.

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...

php - Best Light server (Linux + Web server + Database) for Raspberry Pi -

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
