Senhores, uma ajuda necessária! Segui todos os passos à risca neste início do curso! Docker compose up -d funciona perfeitamente! VsCode mostra: Your application running on port 8080 is available, porém o web browser não consegue abrir. O navegador Firefox ou o Chrome relata:
- A conexão foi reiniciada. A conexão com o servidor foi reiniciada durante o carregamento da página.
Não mostra, portanto, ou o [ ] ou o olá Vinicius!
Não foi tocada nenhuma linha do código. Este erro aparece no 1º exercício!

docker compose logs -f postgres
postgres-1 | Error: in 18+, these Docker images are configured to store database data in a
postgres-1 | format which is compatible with "pg_ctlcluster" (specifically, using
postgres-1 | major-version-specific directory names). This better reflects how
postgres-1 | PostgreSQL itself works, and how upgrades are to be performed.
postgres-1 |
postgres-1 | See also https://github.com/docker-library/postgres/pull/1259
postgres-1 |
postgres-1 | Counter to that, there appears to be PostgreSQL data in:
postgres-1 | /var/lib/postgresql/data (unused mount/volume)
postgres-1 |
postgres-1 | This is usually the result of upgrading the Docker image without
postgres-1 | upgrading the underlying database using "pg_upgrade" (which requires both
postgres-1 | versions).
postgres-1 |
postgres-1 | The suggested container configuration for 18+ is to place a single mount
postgres-1 | at /var/lib/postgresql which will then place PostgreSQL data in a
postgres-1 | subdirectory, allowing usage of "pg_upgrade --link" without mount point
postgres-1 | boundary issues.
postgres-1 |
postgres-1 | See https://github.com/docker-library/postgres/issues/37 for a (long)
postgres-1 | discussion around this process, and suggestions for how to do so.
