失效

突然发现 docker completion 不好用了

但也不是完全的失效，比如docker<tab>里没有 image 了

docker stop<tab>并不列出容器列表了，只有当前目录列表

原因出在 docker 24 的版本更新，官方建议了一种新的方法来生成 completion

但体验是真的不好，所以有老哥打了回到过去的补丁

1
zstyle ':omz:plugins:docker' legacy-completion yes

在 plugins=(…) 之前加即可，如果没有生效可以清除一些缓存

Use old-style completion

Completion is not working properly with Docker version 24.0.2 #11789

在 HelloGithub 上看了这个项目 https://github.com/lucavallin/barco

跳过 formatter, linter 直接改成 gcc 试了一下

有报错

16:41:20 ERROR ./src/cgroups.c:82: failed to open /sys/fs/cgroup/barcontainer/cpu.weight: No such file or directory
16:41:20 FATAL ./src/barco.c:133: failed to initialize cgroups

查后发现

子层级的cgroup资源限制范围被上一级的cgroup.subtree_control文件内容所限制

于是

1
echo '+cpu' > /sys/fs/cgroup/cgroup.subtree_control

正常了！

对端版本为 OpenSSH_5.3p1, OpenSSL 1.0.1e-fips 11 Feb 2013

ssh 报错

1
no matching host key type found. Their offer: ssh-rsa,ssh-dss

在 ssh config 中添加

HostKeyAlgorithms +ssh-rsa

后仍报错

需要添加如下两条配置

HostKeyAlgorithms +ssh-rsa

两个问题，原因是一样的

为什么 docker mysql 建出来的 /var/lib/mysql 用户是 systemd-coredump

是 systemd-coredump 只是碰巧而已

因为 mysql 容器内的 mysql 用户 ID 是 999

1
2
# passwd in mysql container
mysql:x:999:999::/var/lib/mysql:/bin/bash

而主机上的 999 为 systemd-coredump

1
2
# passwd on host
systemd-coredump:x:999:997:systemd Core Dumper:/:/sbin/nologin

为什么 percona-xtrabackup 备份容器中的 mysql 显示无权限

因为 percona-xtrabackup 容器内的 mysql 用户又是其它 ID

# passwd in xtrabackup container
systemd-coredump:x:999:997:systemd Core Dumper:/:/sbin/nologin
mysql:x:1001:1001:Default Application User:/home/mysql:/sbin/nologin

可以在 docker run 时指定用户 -u 解决这个问题

1
docker run --rm -u 999:999 --volumes-from [some-mysql] -v ./backup:/backup percona/percona-xtrabackup xtrabackup --backup --datadir=/var/lib/mysql/ --target-dir=/backup --user=user --password=password

brew 4.0.0 之后运行 doctor 显示

Warning: Some installed kegs have no formulae!
This means they were either deleted or installed manually.
You should find replacements for the following formulae:
  pycparser
  cffi
  erdtree

虽然没什么影响但看着不爽

可以通过brew untap homebrew/core解决

原因是

It removes the local copy of the tap repository (see manpage). This is fine if you do not work on the repository, because the default option since brew 4.0.0 is to fetch formulae information from the JSON API (see 4.0.0 release notes). If you run brew doctor, you should see that the homebrew/core tap has not been updated for a while.

大致就是走 JSON API 了，homebrew/core 也不维护升级了，所以本地那份也别留着了
