[英]Kubernetes Postgres Bus error (core dumped)
I am deploying pgadmin and postgres on kubernetes.我在 kubernetes 上部署 pgadmin 和 postgres。 When i look at deployments I see that 2 deployments are not ready.
当我查看部署时,我发现 2 个部署尚未准备好。 When I look at logs of Pgadmin, I see that it gives error as it can not connect to postgres.
当我查看 Pgadmin 的日志时,我发现它给出了错误,因为它无法连接到 postgres。 I use configmap to connect pgadmin to postgres.
我使用 configmap 将 pgadmin 连接到 postgres。 When I look at logs of postgres I see error.
当我查看 postgres 的日志时,我看到了错误。

After analysing the comments it looks like below resources have been helpful to solve this problem:分析评论后,看起来以下资源有助于解决此问题:
To sum up, editing /usr/share/postgresql/postgresql.conf.sample
file while postgres runs inside a container can be done by putting a custom postgresql.conf
in a temporary file inside the container and overwriting the default configuration at runtime as described here .总而言之,当 postgres 在容器内运行时编辑
/usr/share/postgresql/postgresql.conf.sample
文件可以通过将自定义postgresql.conf
放在容器内的临时文件中并在运行时覆盖默认配置来完成,如所述在这里。 Also, keeping a dummy entry point script using "play with kubernetes" websites and then spinning up the container or trying to copy the file to the container might be useful.此外,使用“玩 kubernetes” 网站保留一个虚拟入口点脚本,然后启动容器或尝试将文件复制到容器中可能会很有用。
