Steps to Reproduce
Define a simple container like this

const { MySqlContainer } = require('@testcontainers/mysql');

const mysqlContainer = await new MySqlContainer()
    .withRootPassword(sqlPassword)
    .withDatabase(sqlDB)
    .withEnvironment('MYSQL_HOSTNAME', sqlHostName) // Manually add the env var
    .withNetworkAliases(sqlHostName)
    .withExposedPorts(3306)
    .withReuse()
    .withCommand(['sh', '-c', 'printenv && sleep 10'])
    .start();
  • see the logs i shared, there is no MYSQL_HOSTNAME env var, happens in all my containers when adding env variables with this function, i have to use command line to do it

Okay, thanks, my bad copilot was suggesting the wrong format all the time

.withEnvironment({ MYSQL_HOSTNAME: sqlHostName }) is the correct line.

Thanks!
