can not open mongo-express

[wzhi05]

I compose up the docker-compose.yml in serving-database and set
rs.initiate(
{
_id : 'rs0',
members: [
{ _id : 0, host : "mongo1:27017" },
{ _id : 1, host : "mongo2:27017" },
{ _id : 2, host : "mongo3:27017" }
]
}
)

But I still can not open mongo-express in port 8083
Following is logs from mongo-express
