pgchief

I don't need an entire web application to manage some self-hosted postgres servers.

I also don't have the entirety of every PG command to back up and restore databases, manage users, assign permissions to databases, etc, catalogued in my brain. (That space is reserved for ... I don't know, obscure comic book characters)

Now, what would be helpful? That is to have something that assists in some of those DB maintenance tasks with a clean and straight-forward CLI interface.

Hence, why I am making this pgchief thing. It's a simple ruby script utilizing the tty-prompt ruby gem to collect necessary info, and do the proper work for me.

NOTE: Very little has been built. This is in active pre-alpha development. See below for the feature check-list and current progress.

gem install pgchief

# To initialize the config file at `~/.config/pgchief/config.toml`:

pgchief --init

# edit the config file and set your main administrative connection string
# (vim|nano|pico|ed) ~/.config/pgchief/config.toml

# OR ... make sure the DATABASE_URL env is set to the connection string
# export DATABASE_URL=postgresql://postgres:password@postgres.local:5432

pgchief

Format of ~/.config/pgchief/config.toml

# Connection string to superuser account at your PG instance
pgurl = "postgresql://username:password@host:5432"

# Directory where db backups will be placed
backup_dir = "~/.pgchief/backups"

# ** OPTIONAL **

# Location of encrypted database connection strings
# credentials_file = "~/.pgchief/credentials"

Note:

1. Prompts accept both ↑ and ↓ arrows, as well as j and k.
2. Pressing the esc key at any point amidst a prompt will exit out of the program.

1. Clone this repo.
2. bundle install
3. cp .env.sample .env
4. Edit .env and change:
   • DATABASE_URL to point to your main pg instance's superuser account with a connection string.
   • TEST_DATABASE_URL to point to your local pg instance where tests can be run against.
5. bundle exec rake to run test suite & rubocop.

$ pgchief --init # create the TOML file in your home dir (w/600 permissions)
$ pgchief
