Testcontainers performance slower than plain docker

Question

I have the following scripted out and it works, but it was suggested that I try using testcontainers.

function die { mvn docker:stop ; exit 1; }

function initializeDatabase {
   docker exec -it mysql-1 mysql -uroot -proot \
   -e "DROP USER IF EXISTS 'myuser'@'%';" \
   -e "DROP DATABASE IF EXISTS mydb;" \
   -e "CREATE DATABASE mydb;" \
   -e "CREATE USER 'myuser'@'%' IDENTIFIED WITH mysql_native_password BY 'mypassword';" \
   -e "GRANT ALL PRIVILEGES ON mydb.* TO 'myuser'@'%';"
}

mvn docker:start && sleep 10

initializeDatabase || die

mvn liquibase:update@execution1 || die

initializeDatabase || die

mvn liquibase:update@execution2 || die

initializeDatabase || die

mvn liquibase:update@execution3 || die

initializeDatabase || die

mvn liquibase:update@execution4 || die

initializeDatabase || die

mvn liquibase:update@execution5 || die

initializeDatabase || die

mvn liquibase:update@execution6 || die

mvn docker:stop

The above takes about 6 minutes to run. It starts a docker container running mysql and initializes the database and runs some liquibase migrations against it 6 different times, mimicking 6 different environments. It takes a little over 6 minutes to run. From Java, using testcontainers and the liquibase java API, it takes over 10 minutes to run. Any thoughts on how I can improve the performance of my testcontainers implementation? I don't think it's liquibase because it's the same liquibase code being invoked behind the scenes.

Below is my code:
