v0.2.1

• Reverted to upstream OCI spec parsing library.

v0.2.0

• All options are now prefixed with --oi in order to avoid name conflicts with underlying runtime options. For example, --readonly-networking-mounts is now called --oi-readonly-networking-mounts.
• Fixed an issue where rewriting a container's config resulted in clone3 syscalls failing. This was due to an issue in the OCI spec parsing dependency. This release uses a forked version of the library, pending acceptance of an upstream PR to resolve the issue.
• Added the ability to override environment variables (--oi-env, --oi-env-force).
• Added optional debug output when modifying container configs (--oi-write-debug-output).

v0.1.0

Initial release. The --readonly-networking-mounts flag is supported, which causes /etc/hosts, /etc/hostname, and /etc/resolv.conf to be mounted as readonly. Typically, Docker will mount these files as read-write, which can be problematic for containers with a writable layer size quota.
