Where to set default environment variables in Alpine linux?

I know that with Ubuntu you can set default values ​​for environment variables in /etc/environment ; I do not see this file in Alpine linux. Is there another place to set system-wide defaults?

It seems that /etc/profile is the best place I could find. At least some environment variables are set there:

 export CHARSET=UTF-8 export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin export PAGER=less export PS1='\h:\w\$ ' umask 022 for script in /etc/profile.d/*.sh ; do if [ -r $script ] ; then . $script fi done

According to the contents of /etc/profile you can create a file with the extension .sh in /etc/profile.d/ and you need to pass --login each time to load env variables, for example docker exec -it container sh --login .

If you are talking about an Alpine Docker image, then you can define these env variables inside the Dockerfile, as shown below. Here you do not need to go through --login every time. These variables will be automatically available throughout the system.

 FROM alpine ENV GITHUB_TOKEN=XXXXXXXXXXXXXXXXXXXXXXX \ COMPOSER_HOME=/home/deploy/.composer

You can also define your alias, env, etc. Inside / etc / profile and define the ENV inside the Dockerfile, as shown below, to automatically create a profile.

 FROM alpine ENV GITHUB_TOKEN=XXXXXXXXXXXXXXXXXXXXXXX \ COMPOSER_HOME=/home/deploy/.composer ENV ENV="/etc/profile"
