tako store¶

Add a new image version to a server directory.

Synopsis¶

tako store [-k <key> | -f <file>] --output <dir> [--] <image> <version>
tako store -h | --help

Description¶

This commands adds a new file to the store and updates the manifest. It computes the SHA256 of the <image> file and copies it into <dir>/store using the hash as filename. Tako then adds an entry to the manifest in <dir> that specifies that <version> corresponds to the computed hash. Tako signs the updated manifest with the provided secret key.

See Versions for information on how Tako treats <version>. For proper ordering, versions should start with a digit: use 1.0.0 rather than v1.0.0. The version must not contain spaces.

The secret key which is used to sign the manifest can be provided in thee ways:

• By setting the TAKO_SECRET_KEY environment variable.
• By passing the secret key directly on the command line with --key.
• By reading the secret key from a file with --key-file.

Command-line options take precedence over the environment variable. A key pair can be generated with tako gen-key.

Options¶

-k --key <key>¶

Provide the secret key <key> directly.

-f --key-file <file>¶

Read the secret key from <file>.

-o --output <dir>¶

Specifies the server directory. <dir> must exist. This must be a path on the file system, uris are not supported. Tako will create <dir>/manifest and <dir>/store if they do not exist yet.
