Tôi có ba mục tổng số. Chỉ một trong số họ có trường CONTAINER_ID tùy chỉnh.
Tôi muốn xây dựng một lệnh tạp chí sẽ loại trừ bất kỳ mục nào có trường cụ thể này đi kèm. Tôi đã thử những điều sau đây nhưng không có kết quả:

Đặt bộ lọc thành CONTAINER_ID=
sẽ trở lại Không mục.
có cách nào để nói không journalctl
để chỉ khớp với các mục đừng có một lĩnh vực hiện tại?
Trang man của tạp chí dường như không liệt kê các ví dụ bao gồm trường hợp sử dụng này.
journalctl -u docker -o json | jq -cMr 'select(has("CONTAINER_ID") | not) | .MESSAGE'
