exec action
This action allows to run a single command in a single container instead of loading a full interactive shell.
When this action is used it is possible to execute a command either in:
a temporary container created especially to execute the command, and automatically deleted at the end of the execution: the name of an exegol image must be provided from which a temporary container will be created
a standard Exegol container (already existing, or not): the name of an exegol container must then be provided. This container will be created in interactive mode if it does not already exist
The executed command can be executed either:
in the background mode (i.e. like a daemon): exegol terminates immediately after the command is launched and does not wait for its execution to be completed. No process is left hanging (useful when running GUI apps for instance).
in standard mode: exegol will wait for the end of the process to stop the container (and delete it if
Tip
In standard execution mode, it is possible to ask exegol to display the command output (stdout/stderr) in the terminal by adding -v parameter.
Options
