We saw in the previous article how to use SOPS to store our secrets in Git. Here, we will see some common operations required when you are using SOPS.
Alice would like to change the value in
dev_a secret. To do so, she can use the
sops dev_a.encrypted.env command to open the
$EDITOR and allow in-place changes.
After the edition, the secret is encrypted back, and she can commit the file in Git.
Alice would like to let
Bobby read the
dev_a secret. To do that, she will use
sops --rotate --in-place --add-pgp <bobby-key-id> dev_a.encrypted.env command.
After this modification,
Bobby can fetch modifications. He is now able to read (and modify) the secret.
Alice now wants to remove
Bobby access to
dev_a secret. She is able to do this by using the
sops --rotate --in-place --rm-pgp <bobby-key-id> dev_a.encrypted.env.
Bobby is unable to decrypt the secret anymore.
Like we saw before,
sops commands often requires references to
key-id of people concerned by the modification... and this is error prone and hard to manage if you share access with a lot of people.
To simplify this, the team can create a file, named
.sops.yaml and placed it in the root of our Git repository.
creation_rules: # Specific to `dev_a` env - path_regex: dev_a\.encrypted\.env$ # Here, only the `Alice` key-id pgp: >- 5844C613B763F4374BAB2D2FC735658AB38BF93A # Specific to `int` env - path_regex: int\.encrypted\.env$ # Here, we have : # * `Alice` key-id: 5844C613B763F4374BAB2D2FC735658AB38BF93A # * `Bobby` key-id: AE0D6FD0242FF896BE1E376B62E1E77388753B8E # * `Devon` key-id: 57E6DA39E907744429FB07871141FE9F63986243 pgp: >- 5844C613B763F4374BAB2D2FC735658AB38BF93A, AE0D6FD0242FF896BE1E376B62E1E77388753B8E, 57E6DA39E907744429FB07871141FE9F63986243 # Specific for new env `dev_a_and_b` - path_regex: dev_a_and_b\.encrypted.env$ # Here, we have only `Alice` and `Bobby` : # * `Alice` key-id: 5844C613B763F4374BAB2D2FC735658AB38BF93A # * `Bobby` key-id: AE0D6FD0242FF896BE1E376B62E1E77388753B8E pgp: >- 5844C613B763F4374BAB2D2FC735658AB38BF93A, AE0D6FD0242FF896BE1E376B62E1E77388753B8E
Bobby will create a new secret for
dev_a_and_b env just with the command
sops dev_a_and_b.encrypted.env. No more
sops automatically selects the closest
.sops.yaml file from the
CWD (see this).
Keys are selected by matching a
regex againt the path of the file, so possibilities are wide and this is simpler than using parameters in command line !
.sops.yaml file is used,
Alice can simplify the
rm-pgp command previously seen. She just need to change the
.sops.yaml and use the command
sops updatekeys dev_a.encrypted.env to update who can decrypt the file.
Those are the most common operations required to use
sops in your project. This is simple and still helps you to keep your secrets in sync with your code !
