PostreSQL password

[Kanezal]

setup this repo to my github codespace in devcontainer.json, in features. Also restart postgresql service to run postgres. So, what the postgres user password? How can I manage it?

You should be able to access PostgreSQL directly but if still didn't work, please check the environment variables exported within your dev container here.

Hi @itsmechlark I had similar issue too. After setting up the postgresql service, I tried to login but got prompted for passoword. I tried vscode, codespace, and postgres but wasn't authenticated cause it was incorrect. I even add sudo at the front of psql -U postgres and still have to input password

Please do you mind telling me what I might not be doing well?

My devcontainer.json

{
  "features": {
    "ghcr.io/itsmechlark/features/postgresql:1.5.0": {}
  }

}

This is what I later did. I had to modified the pg_hba.conf file

.devcontainer/setup-postgres.sh

#!/usr/bin/env bash

# Get version number
major_version_number=$(psql --version | cut -d' ' -f3 | cut -d'.' -f1)

# Path to the pg_hba.conf file
PGHBA_CONF="/etc/postgresql/${major_version_number}/main/pg_hba.conf"

# Backup the original configuration file
cp $PGHBA_CONF ${PGHBA_CONF}.bak

# Modify the pg_hba.conf file to use 'trust' authentication
cat <<EOF > $PGHBA_CONF
# Database administrative login by Unix domain socket
local   all             all                                     trust

# "local" is for Unix domain socket connections only
local   all             all                                     trust

# Allow replication connections from localhost, by a user with the

host    replication     all             127.0.0.1/32            trust

EOF

# Restart PostgreSQL to apply changes
sudo service postgresql restart

echo "PostgreSQL configuration updated and service restarted."
