It's like the env on my DB params, how to build image in docker that can read env when I want to run with this command ?
docker run -e MYSQL_HOST=172.17.0.1 -e MYSQL_USER=xxxx -e MYSQL_PASWORD=xxxx -e MYSQL_DBNAME=todo -p 8090:3030 agamtheos/todo-skyshi
this is my Dockerfile :
FROM node:12-alpine
RUN apk update
RUN mkdir /todo-skyshi
ADD . /todo-skyshi
WORKDIR /todo-skyshi
RUN npm update
RUN ["npm", "start"]
Appreciate for any answer
ReferenceError: DB_NAME is not defined #11 2.247 at Object. (/todo-skyshi/config/database/dbConn.js:4:26).
Abobe error clearly says that variables you are trying to access are not defined.
Env variables name passed in docker run command are different than used in code. DB_NAME, DB_USERNAME,DB_PASSWORD. For example
DB_NAME can be accessed as process.env.MYSQL_DBNAME and so other env variables.
