How do I use environment variables in Travis CI YAML?

You can define environment variables in your .travis.yml file under the env section. For example:

env:
  global:
    - MY_VAR=value
    - ANOTHER_VAR=another_value

Can I use secrets as environment variables?

env:
  global:
    - secure: "encrypted_value"

How do I access these variables in my build?

You can access the environment variables in your build scripts just like any other environment variable. For example, in a shell script, you can use $MY_VAR to get the value.

Are there any limitations on environment variables?

Yes, there are some limitations, such as the maximum number of environment variables and their length. It's best to check the Travis CI documentation for the latest details.
