You can use an existing vault-server or launch a new one using docker-compose

Scripts for configuring the vault-server are located in the vault-init.sh

• instructions for starting and configuring a new vault-server

# Clone the repository
git clone https://github.com/obervinov/pyinstabot-downloader.git
cd pyinstabot-downloader

# Run vault-server
docker-compose -f docker-compose.yml up vault-server -d

# Initialize and unseal new vault-server
export VAULT_ADDR=http://0.0.0.0:8200
vault operator init
vault operator unseal

# Run the script for configuring the vault-server for this bot project
export VAULT_TOKEN=hvs.123456qwerty
./scripts/vault-init.sh

• instructions for configuring an existing vault server

# Clone the repository
git clone https://github.com/obervinov/pyinstabot-downloader.git
cd pyinstabot-downloader

# Run the script for configuring the vault-server for this bot project
export VAULT_ADDR=https://vault.example.com:8200
export VAULT_TOKEN=hvs.123456qwerty
./scripts/vault-init.sh

Bot persistent data storage

Persistent data storage is implemented using Postgresql

• data structure, tables and assignment of tables here
• migrations here

The database structure is created automatically when the bot starts:

1. bot checks the database structure and creates missing tables if necessary
2. after checking the database structure, the bot executes the migrations in the order of their numbering

To quickly prepare an instance, you can execute the psql-init.sh script

git clone https://github.com/obervinov/pyinstabot-downloader.git
cd pyinstabot-downloader

export PGHOST=<host>
export PGPORT=<port>
export PGUSER=<user>
export PGPASSWORD=<password>
export PGDATABASE=postgres
./scripts/psql-init.sh

What data is stored in tables:

• user request queue
• user metadata
• user request logs
• processed messages
• migrations
• bot messages
