commandexecutor

commandexector

CommandExecutors have an important role in this library since they allow us to:

• Execute commands on remote systems like (jump-)hosts reachable over the SSH.
• Execute the same command on the local machine, inside a container (no matter if docker, kubernetes, ...)
• Can be used to short cut the amount of development time since we already know how to do things with redirects in bash or a specific tool...

But it has downsides:

• It's not real programming, it's abusing golang for scripting automation.
• It's a security risk. Calling exec (especially with unchecked user input as parameter) leads to security issues.

Avoid exec calls.

To avoid exec calls on the local machine set the env var accordingly:

export ASCIICHGOLANGPUBLIC_AVOID_EXEC=1

For developers

To run all tests use:

bash -c "cd $(git rev-parse --show-toplevel) && go test -v ./pkg/commandexecutor/..."
