Testcontainers performance slower than plain docker - liquibase

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:

import liquibase.database.jvm.JdbcConnection;
