#

New line is missing in the end of the file when mounting file as secret directly

#

ssh-key-2 is loaded from CurrentModule() and ssh-key is passes as secret to module

dagger call test-fail --ssh-key file:id_ed25519 terminal
/ # cat ssh-key-2
-----BEGIN OPENSSH PRIVATE KEY-----
...
-----END OPENSSH PRIVATE KEY-----
/ # cat ssh-key
-----BEGIN OPENSSH PRIVATE KEY-----
...
-----END OPENSSH PRIVATE KEY-----/ #

#

to reproduce, just remove space from ssh key contents

func (m *SshKeyRepro) TestOkToo(ctx context.Context) *Container {
    sshKeyContents, _ := dag.CurrentModule().Source().File("id_ed25519").Contents(ctx)

    sshKey := dag.SetSecret("ssh-key", strings.TrimSpace(sshKeyContents))

    return dag.
        Wolfi().
        Container(WolfiContainerOpts{
            Packages: []string{"git", "openssh"},
        }).
        WithMountedSecret("/ssh-key", sshKey).
        WithExec([]string{"ssh-keygen", "-y", "-f", "/ssh-key"})
}

🤔 who's adding the newline in the first case? Given that file doesn't seem to have it? https://github.com/sagikazarmark/daggerverse/pull/75/files#diff-be3e511fdda41f50bf714c70d2f2f4e781454e90cc71acafe6d2d6c85ed85d4e

UI is confusing a little bit. My local clone shows newline at the end of the file
