I try to switch all my app to docker.

The configuration:

I used nginx as server. With docker i will use it as proxy:

# nginx -v
nginx version: nginx/1.4.6 (Ubuntu)

Docker version:

# docker version
Client:
 Version: 1.11.1
 API version: 1.23
 Go version: go1.5.4
 Git commit: 5604cbe
 Built: Tue Apr 26 23:30:23 2016
 OS/Arch: linux/amd64

Server:
 Version: 1.11.1
 API version: 1.23
 Go version: go1.5.4
 Git commit: 5604cbe
 Built: Tue Apr 26 23:30:23 2016
 OS/Arch: linux/amd64

# docker-compose -version
docker-compose version 1.7.1, build 0a9ab35

The install:

To install piwik, i use the file suggest here:
indiehosters/piwik

But i made some change because i would like:
- i would like to use a custom db so i configure an additional user and a password.
- i would like to use different containers of mysql by app so i change db to piwik_db (i am not sure it's a good practice)
- i would like to get a phpmyadmin access but i don't understand to make it work with the point 2. So i remove the config part.

So my docker compose fil looks like this:

piwik_db:
 image: mysql
 volumes:
 - ./mysql/runtime:/var/lib/mysql
 environment:
 MYSQL_ROOT_PASSWORD: P@ssR00t
 MYSQL_DATABASE: analytics
 MYSQL_USER: admin
 MYSQL_PASSWORD: P@ssUser
app:
 image: piwik
 links:
 - piwik_db:mysql
 volumes:
 - ./config:/var/www/html/config
 - ./ssmtp.conf:/etc/ssmtp/ssmtp.conf
 - ./revaliases:/etc/ssmtp/revaliases
web:
 image: nginx
 volumes:
 - ./nginx.conf:/etc/nginx/nginx.conf:ro
 - ./etc/letsencrypt:/etc/letsencrypt
 links:
 - app
 volumes_from:
 - app
 ports:
 - "8000:443"
cron:
 image: piwik
 links:
 - piwik_db:mysql
 volumes_from:
 - app
 entrypoint: |
 bash -c 'bash -s <<EOF
 trap "break;exit" SIGHUP SIGINT SIGTERM
 while /bin/true; do
 su -s "/bin/bash" -c "/usr/local/bin/php /var/www/html/console core:archive" www-data
 sleep 3600
 done
 EOF'

The result:

When i run docker-compose up, it finish with an error:

ERROR: for web rpc error: code = 2 desc = "oci runtime error: could not synchronise with container process: not a directory"
Traceback (most recent call last):
 File "<string>", line 3, in <module>
 File "compose/cli/main.py", line 63, in main
AttributeError: 'ProjectError' object has no attribute 'msg'
docker-compose returned -1

When i test which containers was installed, i get

# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
f0388c2a89d3 piwik "bash -c 'bash -s <<E" About a minute ago Up 59 seconds 9000/tcp htdocs_cron_1
ef5d6c8c6e74 mysql "docker-entrypoint.sh" About a minute ago Up About a minute 3306/tcp htdocs_piwik_db_1

Why i get the error?
How to achieve the install?
How to make the app always running?

Thank you in advance for any help.

Ps: I still use my nginx config in site-available:

server 
 listen 80;
 listen [::]:80;

 server_name piwik.domain.com;
 # Redirige le HTTP vers le HTTPS #
 return 301 https://$server_name$request_uri;

server setup/libs) 
 deny all;
 return 404;
 

 # Pass the PHP scripts to FastCGI server
 location ~* .php$ 
 # Prevent Zero-day exploit
 try_files $uri =404;
 #
 fastcgi_split_path_info ^(.+?.php)(/.*)$;
 if (!-f $document_root$fastcgi_script_name) 
 return 404;
 
 fastcgi_pass unix:/var/run/php5-fpm.sock;
 fastcgi_index index.php;
 fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
 include /etc/nginx/fastcgi_params;
 

 # Redirect server error pages to the static page
 error_page 403 /403.html;
 error_page 404 /404.html;
 error_page 500 502 503 504 /50x.html;

 # Exclude from the logs to avoid bloating when it's not available
 include drop.conf;

In my case the problem was because in compose file it was trying to mount files and not folders, changing it solved the issue
