MySQL in Docker seems slow to start 🤔

test_mysql_docker.sh

#!/bin/bash
set -euo pipefail

wait_for_container() {
  echo -n "Waiting for $1"
  for _ in $(seq 1 120); do
    test "$(docker inspect --format "{{.State.Health.Status}}" "$1")" == "healthy" && break
    sleep 1
    echo -n .
  done

  echo

  if test "$(docker inspect --format "{{.State.Health.Status}}" "$1")" != "healthy" ; then
    echo "error: $1 did not become ready" 1>&2
    exit 1
  fi
}

docker run -d --rm --name mysql -p 3306:3306 \
  --health-cmd='mysqladmin ping --silent' \
  -e MYSQL_ALLOW_EMPTY_PASSWORD=true \
