Bom dia.
Na atividade no video "Docker e Postgres", estou tendo dificuldade na conexao do banco de dados. Quando executo o comando "docker-compose up" pelo terminal, ele faz a execução normalmente, porém pelo Docker apenas a porta 54321:80 do PgAdmin está rodando, já a porta 5432:5432 do Postgres não roda, tentando executar ela manualmente torna o erro abaixo:
Error: in 18+, these Docker images are configured to store database data in a
format which is compatible with "pg_ctlcluster" (specifically, using
major-version-specific directory names). This better reflects how
PostgreSQL itself works, and how upgrades are to be performed.
See also https://github.com/docker-library/postgres/pull/1259
Counter to that, there appears to be PostgreSQL data in:
/var/lib/postgresql/data (unused mount/volume)
This is usually the result of upgrading the Docker image without
upgrading the underlying database using "pg_upgrade" (which requires both
versions).
The suggested container configuration for 18+ is to place a single mount
at /var/lib/postgresql which will then place PostgreSQL data in a
subdirectory, allowing usage of "pg_upgrade --link" without mount point
boundary issues.
See https://github.com/docker-library/postgres/issues/37 for a (long)
discussion around this process, and suggest
