How to use docker secret/environment variable in golang dockertest.resource instead of hardcoded pas-CodePudding

We use the below code for unit testing the services that talk to a database system.

MySQL root password is hardcoded in the particular line and creates security issues. Is there any way we can pass that as env variable or docker secret ?

resource, err := pool.Run("mysql", "5.7", []string{"MYSQL_ROOT_PASSWORD=secret"})

CodePudding user response：

You can use the environment variable.

First of all, get the env variable via os.Getenv() in your code

mysqlPwd := os.Getenv("MYSQL_ROOT_PASSWORD")

Then run the docker with the -e option

docker run -e MYSQL_ROOT_PASSWORD=secret
