[emerg] 1#1: host not found in upstream "redash:5000"

Hi,
I was deploying Redash on AWS EB multi-container docker platform.
My Dockerrun.aws.json is:

}
]
}
],
“family”: “”,
“volumes”:
}

When i run “eb run local” to spin the containers locally, get following error:

nginx_1 | 2020/10/24 12:59:05 [emerg] 1#1: host not found in upstream “redash:5000” in /etc/nginx/conf.d/default.conf:2
nginx_1 | nginx: [emerg] host not found in upstream “redash:5000” in /etc/nginx/conf.d/default.conf:2
redash_nginx_1 exited with code 1

All containers are running fine except the redash_nginx_1 with the above error.
