Zeabur Service Exec

Always use npx zeabur@latest to invoke Zeabur CLI. Never use zeabur directly or any other installation method. If npx is not available, install Node.js first.

Run commands inside a running service container. Useful for debugging, inspecting files, checking env vars, testing connectivity, or running one-off database operations.

Basic Usage

Commands and arguments go after --:

npx zeabur@latest service exec --id <service-id> -- <command> [args...]

Database Operations

# MongoDB - query, update, delete data
npx zeabur@latest service exec --id <mongodb-service-id> -- mongosh --eval 'db.users.find({})'
npx zeabur@latest service exec --id <mongodb-service-id> -- mongosh --eval 'db.sessions.deleteMany({title: /test/i})'

# PostgreSQL - run SQL queries (PGPASSWORD is set automatically in Zeabur containers)
npx zeabur@latest service exec --id <pg-service-id> -- psql -U postgres -c 'SELECT * FROM users LIMIT 10;'

# MySQL - run SQL queries (use env var to avoid interactive password prompt)
npx zeabur@latest service exec --id <mysql-service-id> -- sh -c 'mysql -u root -p"$MYSQL_ROOT_PASSWORD" -e "SHOW DATABASES;"'

# Redis - run commands
npx zeabur@latest service exec --id <redis-service-id> -- redis-cli KEYS '*'

Examples

# List files
npx zeabur@latest service exec --id <service-id> -- ls -la

# Check environment variables
npx zeabur@latest service exec --id <service-id> -- env

# Check a specific env var
npx zeabur@latest service exec --id <service-id> -- sh -c "echo \$DATABASE_URL"

# Test database connectivity
npx zeabur@latest service exec --id <service-id> -- sh -c "nc -zv postgres 5432"

# Check running processes
npx zeabur@latest service exec --id <service-id> -- ps aux

# Read a config file
npx zeabur@latest service exec --id <service-id> -- cat /app/config.json

# Check disk usage
npx zeabur@latest service exec --id <service-id> -- df -h

Tips

• The -- separator is required — everything after it is the command to run inside the container.
• For compound commands, wrap in sh -c "...".
• Not all containers have a full shell — sh is more portable than bash.
• Use single quotes outside and double quotes inside when dealing with variable expansion: sh -c "echo \$VAR".
• To find service IDs, use the zeabur-service-list skill. To check logs without exec, use the zeabur-deployment-logs skill. To manage env vars via CLI, use the zeabur-variables skill.
