How to use POSTGRES_PASSWORD_FILE in odoo container? - docker

Question

I need to hide password of postgres in odoo container like in postgres container, when we create new container postgres we can pass env variable POSTGRES_PASSWORD_FILE, and the content of Dockerfile of postgres 9.6 contains this block of code:
#!/usr/bin/env bash
set -Eeo pipefail
# TODO swap to -Eeuo pipefail above (after handling all potentially-unset variables)
# usage: file_env VAR [DEFAULT]
# ie: file_env 'XYZ_DB_PASSWORD' 'example'
# (will allow for "$XYZ_DB_PASSWORD_FILE" to fill in the value of
# "$XYZ_DB_PASSWORD" from a file, especially for Docker's secrets feature)
file_env() {
local var="$1"
local fileVar="${var}_FILE"
local def="${2:-}"
if [ "${!var:-}" ] && [ "${!fileVar:-}" ]; then
echo >&2 "error: both $var and $fileVar are set (but are exclusive)"
exit 1
fi
local val="$def"
if [ "${!var:-}" ]; then
val="${!var}"
elif [ "${!fileVar:-}" ]; then
val="$(< "${!fileVar}")"
fi
export "$var"="$val"
unset "$fileVar"
}
How we can do the same code in odoo image?

Answer 1

You can try to add your whole odoo.conf as a secret, create your service and add that secret with the --secret file and point to the path /run/secrets/${MY_SECRET} on your entrypoint with the -c flag on the odoo command
