This article is about running a service or a command in the background of your CI/CD pipeline with CodeShip Basic. If you’d like to learn more about CodeShip Basic, we recommend the getting started guide or the features overview page.
If you need to run a process in the background during your builds (e.g. to run a service not available by default, or to run a development server provided by your application framework) you can use the following templates to do so.
nohup bash -c "YOUR_COMMAND 2>&1 &"
The above command will run the next step as soon as it finishes. In many cases the server you started isn’t yet fully ready. To allow the server a bit more time to get ready add a
sleep command. How large the argument
sleep needs to be depends on the service you start and you probably need to tweak it.
nohup bash -c "YOUR_COMMAND 2>&1 &" && sleep 4
If you run a command via
nohup it will not print any log output to standard out or standard error. Instead you will see a log line like this.
nohup: ignoring input and appending output to ‘nohup.out’
You also won’t see any error messages printed by the service during startup (or later).
To show error messages during startup, make sure to print the
nohup.out file during your build.
nohup bash -c "YOUR_COMMAND 2>&1 &" && sleep 4 cat nohup.out
For more information see the Ubuntu
nohup man page.
