containers - 在 Ubuntu 20.04 中运行 podman 的问题

Question

不同的问题，主要与用户命名空间的数量有关。

尝试运行预构建的图像会产生:

podman run --rm -it -p8080:8080 --env LOGSTASH_CONF_STRING=$LOGSTASH_CONF_STRING --name logstash bitnami/logstash:latest 
Completed short name "bitnami/logstash" with unqualified-search registries (origin: /etc/containers/registries.conf)

Error: 2 errors occurred while pulling:

所以我真的不能运行这个东西。然后尝试运行一个本地构建的容器来创建我得到的用户:

Error: OCI runtime error: container_linux.go:370: starting container process caused: setup user: invalid argument

配置已设置subuid

jmerelo:100000:65536

虽然

podman unshare cat /proc/self/uid_map
0       1000          1

所以一定有什么东西是我遗漏的，或者我应该在这里重新开始。即使我再次登录，它仍然是相同的结果。所以一定是我在这里做错了什么。
