Not able to start mysql container using docker-compose.yaml file, when I use '$' sign for the MYSQL_ROOT_PASSWORD.
I tried with the other special character '@' and it is starting up.
my docker-compose.yml file
version: '3.3'
services:
database:
container_name: mysql-dev2
image: mysql:8.0
volumes:
- "./data/mysql-dev2:/var/lib/mysql-dev2-docker"
# restart: always
environment:
MYSQL_DATABASE: mysqldb2
MYSQL_ROOT_PASSWORD: Welcome123$
ports:
# <Port exposed> : < MySQL Port running inside container>
- '3307:3306'
expose:
# Opens port 3307 on the container
- '3307'
# Names our volume
volumes:
mysql-dev2:
The error which I am getting F:\docker\mysql-dev2>docker-compose up ERROR: Invalid interpolation format for "environment" option in service "database": "Welcome123$"
If I change the MYSQL_ROOT_PASSWORD to 'Welcome123@', the mysql instance is started running.
help me on this.

You can escape the $ if with a double $$:
...
environment:
MYSQL_DATABASE: mysqldb2
MYSQL_ROOT_PASSWORD: Welcome123$$
