![]() However as we have noted above, this might not work for all cases. This method can also be used to set timezone when using docker compose. ![]() The containers created out of this Dockerfile will have the same timezone as the host OS (as set in /etc/localtime file). This time zone files of the host machine can be set in Docker volume and shared among the containers by configuring it in the Dockerfile as below: volumes: The desired time zone from this folder can be copied to /etc/localtime file, to set as default time. The directory /usr/share/zoneinfo in Docker contains the container time zones available. ![]() Also, instead of making it a part of docker-compose, you can supply it at runtime with docker-compose. For this, we first need to install tzdata package and then specify timezone setting using the environmental variable:Īgain, it depends if the underlying OS has tzdata package installed or not, to support this variable. We can also control container timezone using the Dockerfile. So what said above is true for container engines using containerd. $ docker run -e TZ=Asia/Kolkata alpine:latest dateĭo note that, docker engine uses containerd runtime these days, instead of docker runtime. For alpine based images, it does not work: $ docker run alpine:latest date However, above works only if the image is fedora based. $ docker run -e TZ=Asia/Kolkata ubuntu:latest date For example: $ docker run ubuntu:latest date The timezone of a container can be set using an environment variable in the docker container when it is created. We’ll discuss some of these in this post. Unfortunately, the option to control timezone in the containers / pods can vary, depending upon your container engine, the type of the OS in the container image, the versions of the container engines and platform used to run container engines. Depending on your application and sometimes to meet certain audit requirements, it might be necessary for you to control the timezone in the containers. This means that your container running in London could be reporting that it is running in New York or Singapore, depending on where the image was built. Once the image is pulled, the container engine just launches the container based on the hardcoded time zone. The container image is usually built with a hardcoded link from /etc/localtime to one timezone. When container engines like Podman, Docker or CRI-O run containers, they pull down the specified OCI image from a container registry. If you want to set the local time for the Management Console, please use the TIMEZONE environment variable during creation. By default, Docker and Container uses UTC timezone.
