|

|
|
|

|
|
`docker exec -d {{container_name}} {{command}}`
|
||
|
|
|
||
|
|
- Select the working directory for a given command to execute into:
|

`docker exec -it -w {{path/to/directory}} {{container_name}} {{command}}`
|
||
|
|
|

|
|
|

|
|
`docker exec -i -d {{container_name}} {{command}}`
|

|
|
|
