The default Postgres image has changed and without any
env
variables the healthcheck will never pass.You need to set
POSTGRES_USER
andPOSTGRES_DB
, and may choose to set eitherPOSTGRES_PASSWORD
orPOSTGRES_HOST_AUTH_METHOD
. If you choose to set a password, your Rails test config must specify that password. Alternatively, you can setPOSTGRES_HOST_AUTH_METHOD=trust
to allow all local connections without a password.See docker-library/postgres@42ce743 for more context
