uc exec

Execute a command in a running service container

Synopsis

Execute a command (interactive shell by default) in a running container within a service. If the service has multiple replicas, the command will be executed in a random container.

uc exec [OPTIONS] SERVICE [COMMAND ARGS...] [flags]

Examples

  # Start an interactive shell ("bash" or "sh" will be tried by default)
  uc exec web-service

  # Start an interactive shell with explicit command
  uc exec web-service /bin/zsh

  # List files in the specific container of the service
  uc exec --container d792ea7347e5 web-service ls -la

  # Pipe input to a command inside the service container
  cat backup.sql | uc exec -T db-service psql -U postgres mydb

  # Run a task in the background (detached mode)
  uc exec -d web-service /scripts/cleanup.sh
