pyth: failed to create key_store directory [13 Permission denied]

[Smea1]

When I'm about to create a solana key pair, it says I don't have permission

I have no name!@116c6ad4bcb5:/home/pyth/pyth-client/build$ ./pyth init_key -k $KDIR
pyth: failed to create key_store directory [13 Permission denied]

Make sure the user that's running this has access to $KDIR and that the $KDIR environment variable is well defined.
Do you have more details?

yes,I want to try uploading prices. According to this link：https://docs.pyth.network/publish-data，but when I want to create a solana account after entering docker and running build.sh, it fails.
This is a screenshot of the command：

I have no name!@38d181fe0c9c:/home/pyth/pyth-client/build$ KDIR=$HOME/.pythd

Here is a screenshot of me using the default command

I have no name!@38d181fe0c9c:/home/pyth/pyth-client/build$ ./pythd init_key
