(Also, the reason it defaults to UTC is that in almost all cases, UTC is preferred for servers, and then when presenting a date/time to a user an application would normally convert it to the user’s local time. That’s a tip that has helped me a lot with debugging infrastructure issues. You can often identify when this is happening by debugging with “strange” input that you know will definitely produce different results, for example, if you had run a test using America/New_York then you would have seen that it didn’t work outside of Fly either. Using -v /etc/localtime:/etc/localtime:ro (CentOS) sort of works. How do I configure the containers time zone First, you need both host and guest versions containing this feature, which means running on a 2105B servicing patch or higher. So you can completely remove TZ=Europe/Paris from your Dockerfile!Īlso, a small note for future reference when debugging an issue where something works in one environment but not another: because your host machine is using Europe/Paris it appeared as if ARG was working for you locally (but not on Fly) because it was inheriting the configuration from your environment. I wish to set the timezone of container at docker run time not at docker build/dockerfile time. After I provided my input, it hung there.

It is consistent all around the world, and. command into the Dockerfile) whereas ENV is to set a default value for Environment Variables to be used at runtime – this article is a fantastic breakdown of ARG vs ENV.Ī tiny change should fix this for you: -ARG TZ=Europe/Paris Generally speaking, in my experience most container images are using UTC, which seems like a reasonable default. ARG is for arguments used at build-time (passed from the docker build. The odd thing is that the timestamps for debug messages show the correct local time, as well if I run the 'date' command inside the docker container. The mistake is probably to do with the use of ARG when you need ENV. I am located in UTC -5 (EST), but all my triggers show a timestamp with standard UTC time, 5 hours later than my local time.
