House Keeper

A tool used by Escan members to manage system

go install -v github.com/EscanBE/house-keeper/cmd/hkd@latest

Commands:

Listing files

hkd files list --help

hkd files list --working-directory '/tmp' --order-by date --contains '0' --skip 1

hkd files list --working-directory '/tmp/backup-db' --order-by name --desc --contains '.dump' --skip 3 --silent --delete

Sync files between servers:

hkd files rsync --help

RSYNC_PASSWORD=1234567 hkd files rsync /var/log/nginx/access.log backup@192.168.0.2:/mnt/md0/backup/nginx-logs --local-to-remote

hkd files rsync /var/log/nginx/access.log backup@192.168.0.2:/mnt/md0/backup/nginx-logs --local-to-remote --password-file ~/password.txt

SSHPASS=1234567 hkd files rsync /var/log/nginx/access.log backup-server:/mnt/md0/backup/nginx-logs --local-to-remote --passphrase

Notes:

• This use rsync
• When either source or destination is remote machine:
  • Either environment variable RSYNC_PASSWORD or ENV_SSHPASS or flag --password-file is required (priority flag)
  • Environment variables RSYNC_PASSWORD and ENV_SSHPASS are treated similar thus either needed. If both provided, must be identical
  • You must connect to that remote server at least one time before to perform host key verification (one time action) because the transfer will be performed via ssh.

File checksum:

hkd files checksum --help

hkd files checksum /tmp/test.txt

hkd files checksum /tmp/file_1.txt /tmp/file_2.log /tmp/file_3.docx

hkd files checksum /docs/file_8.txt /logs/file_9.log --cache-and-trust # This will generate /docs/.file_8.txt.hkd-checksum and /logs/.file_9.log.hkd-checksum to save checksum output and prevent future checksum when --cache-and-trust provided again

ls -1 | hkd files checksum [--exclude-dirs]

Perform PostgreSQL DB backup:

hkd db pg_dump --help

PGPASSWORD=1234567 hkd db pg_dump --working-directory /mnt/md0/backup --dbname my_db_name --username my_user_name

hkd db pg_dump --working-directory /mnt/md0/backup --output-file db-2023-01-02.dump --host localhost --port 5432 --dbname postgres --username postgres --schema public --password-file ~/password.txt

Notes:

• Either environment variable PGPASSWORD or flag --password-file is required (priority flag)
• Rely on pg_dump command to perform backup action for PostgreSQL, it actually set environment variable PGPASSWORD and then call pg_dump

Perform PostgreSQL DB restore:

hkd db pg_restore --help

PGPASSWORD=1234567 hkd db pg_restore db-2023-01-02.dump --superuser postgres --dbname example

hkd db pg_restore db-2023-01-02.dump --host localhost --port 5432 --dbname example --username postgres --superuser postgres --password-file ~/password.txt

Notes:

• Either environment variable PGPASSWORD or flag --password-file is required (priority flag)
• Rely on pg_restore command to perform backup action for PostgreSQL, it actually set environment variable PGPASSWORD and then call pg_restore

Config SSH hosts (~/.ssh/config)

hkd config ssh --tsv-input input.tsv --output-file ~/.ssh/hkd_generated_ssh_config --key-root ~/.ssh/id_root --key-user ~/.ssh/id_non_root_users_1 --key-per-user special_user,/home/ubuntu/.ssh/id_special_user

Command aliases

House-keeper defined a set of command aliases to help your life easier

• Listing supported alias by: hkd a
• Invoke alias execution by: hkd a [alias]

Defined your own aliases by create a TSV ~/.hkd_alias

Download file

hkd download --help

hkd dl https://escan.live/images/logo-light.svg

hkd download https://escan.live/images/logo-light.svg --concurrent 4 --output-file logo.svg --working-directory ~/Downloads

Notes:

• Priority download tools: aria2c > wget > curl
• The flag --concurrent is only used when aria2c is used as download tool
• Default concurrent download is 4 for speed up download process
