问题
没有外网,所以配置了一个local custom镜像库,也使用了container-image-metadata-url进行配置,但是用juju创建lxd容器时还是说找不着image.
相关搜索
关于container-image-metadata-url的代码如下:
https://github.com/juju/juju/pull/8578
https://github.com/juju/juju/blob/juju-2.9.35/container/lxd/manager.go#L282-L284
也有一个好帖子:
https://discourse.charmhub.io/t/local-lxd-image-server/3929/5
实验环境
1, 使用 juju创建一个focal的machine 0, 然后再machine 0上部署一个xenial的lxd容器。
juju add-model test
juju add-machine --series focal
juju model-config logging-config="<root>=DEBUG"
juju remove-application ceph-radosgw && juju deploy ceph-radosgw --series=xenial --to="lxd:0"
2, 在juju controller(juju ssh -m controller 0)与machine 0上运行下列iptables来模拟和cloud-images.ubuntu.com断网。这里我发现:
- machine 0的日志(/var/log/juju/machine-0.log)显示它好像是从juju controller处下载镜像的
2023-03-01 07:58:21 INFO juju.cloudconfig userdatacfg_unix.go:613 Fetching agent: curl -sSf --connect-timeout 20 --noproxy "*" --insecure -o $bin/tools.tar.gz <[https://10.5.0.31:17070/model/deb85179-10a6-4877-88f7-012ef768d726/tools/2.9.38-ubuntu-amd64 https://252.0.31.1:17070/model/deb85179-10a6-4877-88f7-012ef768d726/tools/2.9.38-ubuntu-amd64]>

- 但如果不在machine 0上运行下载iptables,测试表明machine0也能直接扰开juju controller从cloud-images.ubuntu.com处下镜像.
- 似乎二者均相关,那就二者将运行下列iptables吧
dig cloud-images.ubuntu.com #185.125.190.37 and 185.125.190.40
juju ssh -m controller 0 -- sudo iptables -A OUTPUT -d 185.125.190.37 -j DROP
juju ssh -m controller 0 -- sudo iptables -A OUTPUT -d 185.125.190.40 -j DROP
cat << EOF |tee test.yaml
cloudinit-userdata: |
postruncmd:
- bash -c 'echo 10.5.0.126 quqi.com >> /etc/hosts'
- bash -c 'iptables -A OUTPUT -d 185.125.190.37 -j DROP'
- bash -c 'iptables -A OUTPUT -d 185.125.190.40 -j DROP'
EOF
juju model-config ./test.yaml
3, bastion上运行sstream-mirror将cloud-images.ubuntu.com中的xenial amd64镜像mirror了下来。
sudo apt -y install simplestreams -y
workdir=/home/ubuntu/simplestreams2
sudo sstream-mirror --keyring=/usr/share/keyrings/ubuntu-cloudimage-keyring.gpg --progress --max=1 --path=streams/v1/index.json https://cloud-images.ubuntu.com/releases/ $workdir 'arch=amd64' 'release~(xenial)' 'ftype~(lxd.tar.xz|squashfs|root.tar.xz|root.tar.gz|disk1.img|.json|.sjson)'
然后用nginx为它配置了https:
#https://goharbor.io/docs/2.6.0/install-config/configure-https/
openssl genrsa -out ca.key 4096
openssl req -x509 -new -nodes -sha512 -days 3650 -subj "/C=CN/ST=Beijing/L=Beijing/O=example/OU=Personal/CN=quqi.com" -key ca.key -out ca.crt

curl --resolve quqi.com:443:10.5.0.126 --cacert ~/ca/ca.crt https://quqi.com:443/streams/v1/index.json
sudo cp ~/ca/ca.crt /usr/local/share/ca-certificates/ca.crt
sudo chmod 644 /usr/local/share/ca-certificates/ca.crt
sudo update-ca-certificates --fresh
curl --resolve quqi.com:443:10.5.0.126 https://quqi.com:443/streams/v1/index.json
$ cat /etc/nginx/sites-available/default

}
}
# 注意:由于上面使用了一个新目录/home/ubuntu/simplestreams2作为root,那需要将/etc/nginx/nginx.conf中添加'user root;'来避免权限问题
#curl --resolve quqi.com:443:10.5.0.126 --cacert ~/ca/ca.crt https://quqi.com:443/images/streams/v1/index.json
curl --resolve quqi.com:443:10.5.0.126 --cacert ~/ca/ca.crt https://quqi.com:443/streams/v1/index.json
4, 配置juju中的container-image-metadata-url使用上面的https based local image mirror
juju model-config container-image-metadata-url=https://quqi.com:443
juju model-config image-metadata-url=https://quqi.com:443
5, juju controller由于访问local image mirror, 所以配置hosts与添加ca key
echo '10.5.0.126 quqi.com' >> /etc/hosts
curl --resolve quqi.com:443:10.5.0.126 --cacert ~/ca/ca.crt https://quqi.com:443/streams/v1/index.json
sudo cp ~/ca/ca.crt /usr/local/share/ca-certificates/ca.crt
sudo chmod 644 /usr/local/share/ca-certificates/ca.crt
sudo update-ca-certificates --fresh
curl --resolve quqi.com:443:10.5.0.126 https://quqi.com:443/streams/v1/index.json
6, 记得重新测试之前将machine 0上的image cache删除
juju ssh 0 -- sudo lxc image delete juju/xenial/amd64
juju remove-application ceph-radosgw
7, 重新测试
juju deploy ceph-radosgw --series=xenial --to="lxd:0"
sudo tail -f /var/log/juju/machine-0.log
能在machine 0的/var/log/juju/machine-0.log中观察下列日志:
2023-03-01 08:26:45 WARNING juju.worker.lxdprovisioner provisioner_task.go:1371 machine 0/lxd/3 failed to start: acquiring LXD image: no matching image found

在juju controller上有时能搜到quqi, 有时候又不能,奇怪.

juju controller上仍然能看到cloud-images.ubuntu.com
2023-03-01 08:34:54 WARNING juju.apiserver.provisioner provisioninginfo.go:801 encountered "http://cloud-images.ubuntu.com/releases/streams/v1/index.sjson": Get "http://cloud-images.ubuntu.com/releases/streams/v1/index.sjson": dial tcp 185.125.190.37:80: i/o timeout while getting published images metadata from default ubuntu cloud images
使用glance中的image来提供simplestreams
上面是使用来提供simplestreams, 我们现在换用glance中的image来提供simplestreams继续测试 (不确定是否这种只适用于创建juju controller, 还是说也可以用于VM/LXD创建,试一下)
mkdir -p ~/simplestreams/images
IMAGE_ID=26751c0e-4282-415e-b8dc-a7a21d2f781d
SERIES=xenial
juju metadata generate-image -d ~/simplestreams -i $IMAGE_ID -s $SERIES -r RegionOne -u $OS_AUTH_URL
然后修改/etc/nginx/sites-available/default将上面测试用的/home/ubuntu/simplestreams2改成/home/ubuntu/simplestreams, 重启nginx之后, 设置container-image-metadata-url (注意:此时后面链接多出了/images)
juju model-config container-image-metadata-url=https://quqi.com:443/images
juju model-config image-metadata-url=https://quqi.com:443/images
#注意下面的并不是由上两句形成的,而是由人工运行lxc命令(lxc remote add xxx)形成的,但即使有它也不 work
root@juju-4e4d8f-test-0:~# cat ~/snap/lxd/common/config/config.yml

protocol: simplestreams
public: true
local:

public: true
aliases: {}
为保证测试环境干净,我也在controller与machine0上运行了下列命令:
systemctl restart jujud-machine-0.service
然后重复测试后,问题依旧, controller上看到下列日志:
2023-03-01 10:29:32 WARNING juju.environs.simplestreams datasource.go:184 Got error requesting "https://streams.canonical.com/juju/tools/streams/v1/index.sjson": Get "https://streams.canonical.com/juju/tools/streams/v1/index.sjson": dial tcp 185.125.190.37:443: i/o timeout

看样子和simplestreams类型无关。
测试cloudinit-userdata
即然与simplestreams类型无关,那我们将nginx再恢复之前的/home/ubuntu/simplestreams2
juju model-config container-image-metadata-url=https://quqi.com:443/
juju model-config image-metadata-url=https://quqi.com:443/
然后测试cloudinit-userdata, 这个是没问题的,可以作workaround
cat << EOF |tee cloudinit-userdata.yaml
cloudinit-userdata: |
postruncmd:
- echo '10.5.0.126 quqi.com' >> /etc/hosts
- if hostname |grep -qv lxd; then wget --tries=15 --retry-connrefused --timeout=15 --random-wait=on -O /home/ubuntu/ubuntu-16.04-server-cloudimg-amd64-lxd.tar.xz https://quqi.com:443/server/releases/xenial/release-20211001/ubuntu-16.04-server-cloudimg-amd64-lxd.tar.xz --no-check-certificate; wget --tries=15 --retry-connrefused --timeout=15 --random-wait=on -O /home/ubuntu/ubuntu-16.04-server-cloudimg-amd64.squashfs https://quqi.com:443/server/releases/xenial/release-20211001/ubuntu-16.04-server-cloudimg-amd64.squashfs --no-check-certificate; fi
- sleep 30
- if hostname |grep -qv lxd; then lxc image import /home/ubuntu/ubuntu-16.04-server-cloudimg-amd64-lxd.tar.xz /home/ubuntu/ubuntu-16.04-server-cloudimg-amd64.squashfs --alias juju/xenial/amd64; fi
EOF
juju model-config ./cloudinit-userdata.yaml
juju model-config cloudinit-userdata --format yaml
#juju model-config --reset cloudinit-userdata
注意:之前一直不work的原因是因为在postruncmd:后加了 | 的原因,找到答案的过程见下列的"调试cloud-init"一节。
调试cloud-init
最后发现用下面的是不work的:
cat << EOF |tee test.yaml
cloudinit-userdata: |
postruncmd: |
- echo '10.5.0.126 quqi.com' >> /etc/hosts
- echo 'test' > /home/ubuntu/cloud-init.txt
EOF
需要改成下面的:
cat << EOF |tee test.yaml
cloudinit-userdata: |
postruncmd:
- bash -c 'echo 10.5.0.126 quqi.com >> /etc/hosts'
- bash -c 'echo test > /home/ubuntu/cloud-init.txt'
EOF
下面的也不会work
cat << EOF |tee test.yaml
cloudinit-userdata: |
postruncmd: |
bash -c 'echo 10.5.0.126 quqi.com >> /etc/hosts'
bash -c 'echo test > /home/ubuntu/cloud-init.txt'
EOF
下面的更不会work, 会直接报:ERROR json: unsupported type: map[interface {}]interface {}’
cat << EOF |tee test.yaml
cloudinit-userdata: |
postruncmd:
bash -c 'echo 10.5.0.126 quqi.com >> /etc/hosts'
bash -c 'echo test > /home/ubuntu/cloud-init.txt'
EOF
其他调试方法如下:
juju add-model test
juju model-config ./test.yaml
juju model-config cloudinit-userdata --format yaml
juju model-config ssl-hostname-verification=false
juju add-machine --series focal
1, check cloud-init log: cloud-init collect-logs & tar -xf cloud-init.tar.gz
2, check cloud-init config: /etc/cloud/cloud.cfg
3, cloud-init is enabled: systemctl list-unit-files | grep cloud
4, /var/lib/cloud/instances/af2d721e-e38e-4937-81ad-7cc72a49c184/cloud-config.txt

lxc remote端的测试
lxc端用cloud-images.ubuntu.com作default ,这个default不能replace,
# lxc remote list |grep releases
| ubuntu | https://cloud-images.ubuntu.com/releases | simplestreams | none | YES | YES | NO |
root@juju-4e4d8f-test-7:~# lxc remote set-url ubuntu https://quqi.com:443
Error: Remote ubuntu is static and cannot be modified
它只能添加,所以我添加了自己的也干脆将它设置成public类型的
lxc remote add test https://quqi.com:443 --protocol=simplestreams
lxc remote remove test & lxc remote add test https://quqi.com:443 --protocol=simplestreams --public
sudo snap set lxd daemon.debug=true
sudo systemctl reload snap.lxd.daemon
也要machine里设置了LXD_INSECURE_TLS=true(remote error: tls: protocol version not supported), 总之确保了使用test mirror (lxc launch test:16.04 i1)能正常运行。
vim /etc/systemd/system/snap.lxd.daemon.service
Environment=LXD_INSECURE_TLS=true
#或者去掉nginx中的ssl_protocols TLSv1.2也行
但是测试还是失败,machine端看到了日志:

20230607更新
今天终于知道 lp bug 2008993中的测试时而可以时而不行的原因了: https://bugs.launchpad.net/juju/+bug/2008993
原来是juju model中配置了juju-https-proxy导致container-image-metadata-url不work,这样:
- 若start nginx (image mirror), machine 0’s jujud will call nginx (node1.lan:443), then ca
138 66.866261 10.0.0.13 → 192.168.99.179 HTTP 159 CONNECT node1.lan:443 HTTP/1.1
140 66.871290 192.168.99.179 → 10.0.0.13 HTTP 111 HTTP/1.1 200 Connection established
160 66.890098 10.0.0.13 → 192.168.99.179 HTTP 187 CONNECT cloud-images.ubuntu.com:443 HTTP/1.1
162 66.896207 192.168.99.179 → 10.0.0.13 HTTP 111 HTTP/1.1 200 Connection established
164 66.896723 10.0.0.13 → 192.168.99.179 TLSv1 341 Client Hello
- 若stop nginx, jujud call nginx的时候返回了’503 Service Unavailable’, 然后CONNECT cloud-images.ubuntu.com:443时会走juju-https-proxy, 所以这是我们为什么在controller与machine0上都设置了iptables rules来block到cloud-images.ubuntu.com:443的流量之后jujud仍然可以下载到image的原因
1 574 62.682108 10.0.0.13 → 192.168.99.179 HTTP 159 CONNECT node1.lan:443 HTTP/1.1

上面的抓包采用下列方法, 它能看到完整的http流:
sudo tcpdump -i any -w capture.pcap'
tshark -r capture2.pcap -Y http
注意,不能用下列的方法分析, 因为它是https流量,看到都指向cloud-images.ubuntu.com很正常,所以用上面的’tshark-rcapture2.pcap -Y http’来分析:
$ tshark -r capture2.pcap -Y "http.request.method == GET" -T fields -e http.host -e http.request.uri |grep 18.04 |grep -v deb

另外一个问题是我是用下列命令创建的image mirror, 它少了bionc,而我却在用bionic做实验。
workdir=/images/simplestreams/lxdkvm
sudo sstream-mirror --keyring=/usr/share/keyrings/ubuntu-cloudimage-keyring.gpg --progress --max=1 --path=streams/v1/index.json https://cloud-images.ubuntu.com/releases/ $workdir 'arch=amd64' 'release~(xenial|focal|jammy)' 'ftype~(lxd.tar.xz|squashfs|root.tar.xz|root.tar.gz|disk1.img|.json|.sjson)'
所以正确的方法还是得在一个multipass虚机中做实验,来隔离一切可能的网络影响,方法如下:
openstack server create --wait --image auto-sync/ubuntu-jammy-daily-amd64-server-20220423-disk1.img --flavor m1.2xlarge --key-name mykey --network=zhhuabj_admin_net test
