Answering for better formatting. The comments suggest sleeping. Assuming this is the dockerfile (https://hub.docker.com/r/bde2020/spark-worker/dockerfile) You could sleep by adding the command:
spark-worker-1:
image: bde2020/spark-worker:2.4.4-hadoop2.7
container_name: spark-worker-1
command: sleep 10 && /bin/bash /worker.sh
depends_on:
- spark-master
ports:
- "8081:8081"
environment:
- "SPARK_MASTER=spark://spark-master:7077"
Although sleep 10 is probably excessive, if this would would sleep 5 or sleep 2
