5. containerd配置优化

为了提高containerd的性能和稳定性，需要进行一些配置优化。

5.1 存储配置优化

# 编辑containerd配置
# vi /etc/containerd/config.toml

# 存储配置
[plugins.”io.containerd.grpc.v1.cri”.containerd]
snapshotter = “overlayfs”
[plugins.”io.containerd.grpc.v1.cri”.containerd.snapshotter]
[plugins.”io.containerd.grpc.v1.cri”.containerd.snapshotter.overlayfs]
upperdir = “/var/lib/containerd/io.containerd.snapshotter.v1.overlayfs/upper”
workdir = “/var/lib/containerd/io.containerd.snapshotter.v1.overlayfs/work”

# 验证配置
# cat /etc/containerd/config.toml | grep -A 10 “snapshotter”

5.2 运行时配置优化

endpoint = [“https://registry.cn-hangzhou.aliyuncs.com”, “https://docker.io”]
[plugins.”io.containerd.grpc.v1.cri”.registry.mirrors.”quay.io”]
endpoint = [“https://quay.io”]
[plugins.”io.containerd.grpc.v1.cri”.registry.mirrors.”gcr.io”]
endpoint = [“https://gcr.io”]

# 验证配置
# cat /etc/containerd/config.toml | grep -A 20 “registry”

5.4 重启containerd服务

# 重启containerd服务
# systemctl restart containerd

# 验证配置生效
# ctr version

6. containerd容器管理

# 创建CNI配置目录
# mkdir -p /etc/cni/net.d

# 创建CNI配置文件
# vi /etc/cni/net.d/10-containerd-net.conflist

{
“cniVersion”: “0.4.0”,
“name”: “containerd-net”,
“plugins”: [
{
“type”: “bridge”,
“bridge”: “cni0”,
“isGateway”: true,
“ipMasq”: true,
“ipam”: {
“type”: “host-local”,
“subnet”: “10.88.0.0/16”,
“routes”: [
{
“dst”: “0.0.0.0/0”
}
]
}
},
{
“type”: “portmap”,
“capabilities”: {
“portMappings”: true
}
}
]
}

# 验证CNI配置
# cat /etc/cni/net.d/10-containerd-net.conflist

7.2 网络故障排查

# 允许容器网络流量
# firewall-cmd –add-masquerade –permanent
# firewall-cmd –reload

8. containerd存储配置

containerd使用存储驱动来管理容器的文件系统，支持多种存储驱动。

8.1 存储驱动配置

# 查看存储驱动
# ctr plugins ls | grep snapshotter
TYPE ID PLATFORMS STATUS
io.containerd.snapshotter.v1 overlayfs linux/amd64 ok

# 编辑containerd配置
# vi /etc/containerd/config.toml

# 存储配置
[plugins.”io.containerd.grpc.v1.cri”.containerd]
snapshotter = “overlayfs”

# 验证存储配置
# cat /etc/containerd/config.toml | grep -A 5 “snapshotter”

8.2 存储优化

# 清理未使用的镜像
# ctr images prune

# 清理未使用的容器
# ctr containers prune

# 查看存储使用情况
# du -sh /var/lib/containerd/
1.2G /var/lib/containerd/

9. containerd性能优化

在生产环境中，需要对containerd进行性能优化以提高容器运行效率。from:www.itpux.com

9.1 内存优化

# 编辑containerd配置
# vi /etc/containerd/config.toml

# 内存配置
[plugins.”io.containerd.grpc.v1.cri”]
[plugins.”io.containerd.grpc.v1.cri”.containerd]
[plugins.”io.containerd.grpc.v1.cri”.containerd.runtimes.runc]
[plugins.”io.containerd.grpc.v1.cri”.containerd.runtimes.runc.options]
MemoryLimit = true

# 重启containerd服务
# systemctl restart containerd

9.2 镜像优化

# 拉取轻量级镜像
# ctr images pull docker.io/library/alpine:latest

# 构建优化的Dockerfile
# vi Dockerfile
FROM alpine:latest
RUN apk add –no-cache nginx
EXPOSE 80
CMD [“nginx”, “-g”, “daemon off;”]

# 使用buildkit构建镜像
# buildctl build –frontend dockerfile.v0 –local context=. –local dockerfile=. –output type=image,name=localhost/fgedu/nginx:alpine

# 查看镜像大小
# ctr images ls | grep fgedu/nginx
REF TYPE DIGEST SIZE PLATFORMS LABELS
localhost/fgedu/nginx:alpine application/vnd.docker.distribution.manifest.v2+json sha256:1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef 15MB linux/amd64

9.3 网络优化

# 编辑CNI配置
# vi /etc/cni/net.d/10-containerd-net.conflist

{
“cniVersion”: “0.4.0”,
“name”: “containerd-net”,
“plugins”: [
{
“type”: “bridge”,
“bridge”: “cni0”,
“isGateway”: true,
“ipMasq”: true,
“mtu”: 1450,
“ipam”: {
“type”: “host-local”,
“subnet”: “10.88.0.0/16”,
“routes”: [
{
“dst”: “0.0.0.0/0”
}
]
}
}
]
}

# 重启containerd服务
# systemctl restart containerd

9.4 存储优化

# 编辑containerd配置
# vi /etc/containerd/config.toml

# 重启containerd服务
# systemctl restart containerd

# 清理存储
# ctr images prune
# ctr containers prune

生产环境建议：根据服务器硬件配置和容器数量调整containerd的资源限制和配置。使用轻量级镜像，合理配置网络和存储，定期清理未使用的资源以提高性能。

11. containerd备份恢复

本节介绍containerd的备份和恢复方法。

11.1 containerd容器备份

# 备份镜像
# ctr images export /backup/images_$(date +%Y%m%d).tar $(ctr images ls -q)

# 备份容器
# for container in $(ctr containers ls -q); do ctr containers export $container /backup/container_${container}_$(date +%Y%m%d).tar; done

11.2 containerd容器恢复

# 恢复配置
# cp -r /backup/containerd_20240405 /etc/containerd

# 恢复镜像
# ctr images import /backup/images_20240405.tar

# 启动containerd服务
# systemctl start containerd

# 验证恢复
# ctr images ls

11.3 containerd监控脚本

# 创建containerd监控脚本
# vi /data/containerd/scripts/containerd_monitor.sh

#!/bin/bash
LOG_FILE=”/var/log/containerd_monitor.log”
ALERT_EMAIL=”admin@fgedu.net.cn”

check_containerd_status() {
echo “$(date): Checking containerd status…” >> $LOG_FILE
status=$(systemctl status containerd | grep -o “Active: active”)
if [ “$status” = “Active: active” ]; then
echo “$(date): containerd status: OK” >> $LOG_FILE
else
echo “$(date): containerd status: FAILED” >> $LOG_FILE
echo “containerd service failed” | mail -s “containerd Alert” $ALERT_EMAIL
fi
}

check_container_status() {
echo “$(date): Checking container status…” >> $LOG_FILE
containers=$(ctr containers ls -q | wc -l)
echo “$(date): Running containers: $containers” >> $LOG_FILE
if [ “$containers” -eq 0 ]; then
echo “$(date): No containers running” >> $LOG_FILE
echo “No containers running” | mail -s “containerd Alert” $ALERT_EMAIL
fi
}

check_storage_usage() {
echo “$(date): Checking storage usage…” >> $LOG_FILE
usage=$(du -sh /var/lib/containerd/ | awk ‘{print $1}’)
echo “$(date): Storage usage: $usage” >> $LOG_FILE
if [[ “$usage” == *”G”* ]]; then
size=$(echo $usage | sed ‘s/G//’)
if (( $(echo “$size > 50” | bc -l) )); then
echo “$(date): Storage usage too high: $usage” >> $LOG_FILE
echo “Storage usage too high: $usage” | mail -s “containerd Alert” $ALERT_EMAIL
fi
fi
}

main() {
check_containerd_status
check_container_status
check_storage_usage
}

main

# 添加执行权限
# chmod +x /data/containerd/scripts/containerd_monitor.sh

# 添加定时任务
# crontab -e
*/15 * * * * /data/containerd/scripts/containerd_monitor.sh

生产环境建议：定期备份containerd容器和镜像，建议每天执行一次完整备份。监控脚本建议每15分钟执行一次，及时发现并处理问题。恢复操作前务必停止containerd服务，避免数据不一致。

通过以上步骤，containerd安装配置、性能优化、升级迁移、备份恢复等内容已全部完成。containerd作为行业标准的容器运行时，能够高效地管理和运行容器，是容器化部署的重要组件之一。
