Workloads

HostShift uses workload adapters to plan transfer, target preparation, verification, and rollback metadata.

Supported Workloads

docker-compose
docker-standalone
docker-volume
file-set
cron
php-fpm
supervisor
fail2ban
memcached
rabbitmq
certbot
logrotate
caddy
apache-vhost
systemd-service
mysql
mariadb
postgresql
redis

For every field, generated command, target package capability, and validation rule, see Workload Reference.

Transfer Strategy

Sync plans may include streams, which pipe a validated source read command into a validated target write command.

Examples:

tar --create to tar --extract
docker image save to docker image load
mysqldump to mysql
pg_dump to pg_restore
existing Redis RDB or redis-cli --rdb stream to target RDB file
existing Docker volume snapshot tar to a reviewed target data path

Checks

Verify checks include:

HTTP status checks with optional Host header
Laravel database connectivity through a target-side container command
target-side fileExists and fileContains
MySQL and PostgreSQL scalar checks
systemd serviceActive
UFW and nftables rule checks
Nginx config validation and reload

For every check type and its generated target command, see Check Reference.

Target Package Planning

HostShift derives package requirements from workloads and checks, maps them through the Ubuntu/Debian platform adapter, and blocks unknown target platforms instead of guessing package names.
