# 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)
|
