HOSTING SERVER DETAIL
Hosting provider : OVH
Machine : remote VPS
Server : Apache2.4
OS distro : Ubuntu 22.04 LTS
SERVICES
App image : algoo/tracim:latest
DB server : MariaDB
Network : Docker default bridge Network
Hello,
I am about to execute following “docker run“ command line, but being newbie to docker, I’d like someone to review it and tell if it is correctly edited and functional to run app container of choice, depending external MariaDB server through connection over default bridge network :
docker run --env-file /tracim/.env_named -p 8080:80 - p 3306:3306 -v ~/tracim/etc:/etc/tracim -v ~/tracim/var:/var/tracim algoo/tracim
So to allow whoever wishing to help, the above “docker run“ command line may be reviewed based on here below 5 steps (each one showing how it renders the “docker run“ command line getting build), to configure both the app container and the MariaDB server (on same host).
I’ll be thankful too, to get replies to simple questions ending this post
SERVICES CONFIGURATION
STEP 1 : I did successfully install docker via shell
• sub-step : verify that docker is running - OK
• sub-step : connect and disconnect to docker via terminal using my docker hub account credentials - OK
• sub-step : get my host’s docker IP ADRESS to allow its remote access from container with docker default bridge mode : 172.17.0.1 (next on step 3)
°°° editing cl °°°°
docker run -p 8080:80
STEP 2 : I did install tracim volumes and pull algoo/tracim image via shell, as non-root user (su -)
• sub-step : locate created volumes in Ubuntu OS file system - OK
°°° editing cl °°°°
docker run -p 8080:80 ……. -v ~/tracim/etc:/etc/tracim -v ~/tracim/var:/var/tracim algoo/tracim

STEP 3 : I did create and setup database and user on my host (VPS)
• sub-step : grant all privileges to new user on new database, with remote access from any host (%) - OK
• sub-step : change MariaDB server bind-address to host’s docker IP ADDRESS “172.17.0.1“ - OK
°°° editing cl °°°°
docker run ……. - p 3306:3306 -p 8080:80 -v ~/tracim/etc:/etc/tracim -v ~/tracim/var:/var/tracim algoo/tracim
STEP 4 : I did create .env file in tracim container root directory
• sub-step : extend the .env with a specific name : # sudo nano ./tracim/.env_named - OK
• sub-step : set the .env_named file with the above created MariaDB database environment variable, such as
MYSQL_ROOT_PASSWORD=password
MYSQL_DATABASE=name
MYSQL_USER=user
MYSQL_PASSWORD=password
°°° editing cl °°°°
docker run --env-file /tracim/.env_named -p 8080:80 - p 3306:3306 -v ~/tracim/etc:/etc/tracim -v ~/tracim/var:/var/tracim algoo/tracim

STEP 5 : set firewall (ufw) to allow container’s IP ADRESS to listen on port 3306
• sub-step : verify from cpanel that port 3306 is allowed in firewall - OK
• sub-step : allow traffic and matching between container’s IP ADDRESS and MariaDB server port 3306 (MISSING)
(the container’s IP ADDRESS may only be collected after that the container was run at least once)
QUESTIONS
Q1 : does final “docker run“ command line (step 4) miss configuration parameters, e.g host’s docker IP ?
Q2 : does final “docker run“ command line (step 4) contains parameters that are unnecessary ?
Q3 : is .env_named file (step 4) is correctly configured with on host database environment variable (MariaBD)?
Q4 : may execution of above “docker run“ command line fails because of step 5 (ufw) being unachieved ?
