标签:接口 comm replicas removing docker ati test 解决 参数 创建srvice的参数的时候,如果设置了network参数(接口POST:service/create) 而更新的时候,没有传network参数,会报错:error while removing network:… 更新service参数如下:(接口PUT:/service/update) 同时,因为端口等其他参数也没传,造成更新之后,端口啥的都消失了,截图如下: 1. 创建service的时候 2. 更新service之后 先不考虑端口等其他问题,先分析造成network错误的原因,上面是创建service的时候设置了network参数,下面对应几个更新service的时候传不同参数的结果 总结以上发现,只要是只传部分参数,就会报错,但我又不能每次更新都让调用接口的人把所有的参数传过来,怎么办呢? 大量测试,从全量传参一个一个减少参数,看看到底是哪个参数不传造成的,经过测试发现必须要穿更新配置参数UpdateConfig,并且Parallelism参数(同时更新数)必须设置为1(个人猜测是docker service异步更新造成的?) 既然找到原因了,那么设置成这个参数为非空必传就行了,但是有个问题,每次都要取查询上次的这个参数,比较麻烦,个人解决方案是再程序内部判断接口是否传这个参数 如果接口没传这个参数,内部逻辑代码是主动去查,用查到的填充 如果接口传了这个参数,内部逻辑代码是主动去查,用查到的数据判断有没有network配置,如果有network配置,再去判断传的参数是否设置Parallelism为1,如果不是,提醒接口调用者 最后又做了不等service 的副本容器启动起来,立即更新srvice,报错 service/create service/update 创建参数: 更新参数: 创建参数: 更新参数: 经过测试(没有大量测试),目前发现的是 如果创建service的时候设置network,那么更新service的时候需要传参UpdateConfig参数 如果创建service的时候不设置network,那么更新service的时候,可以不穿UpdateConfig参数 docker API接口service update错误记录 标签:接口 comm replicas removing docker ati test 解决 参数 原文地址:https://www.cnblogs.com/zhzhlong/p/12793028.html一、问题 error while removing network:…

二、分析错误原因
1. 更新的时候 network不变,相当于不更改network,(更改了副本数)
(1)只传部分参数,报错
{ // 更新的时候传的参数
"ServiceId": "9t2jucsc3t1i0t9bx2n7csmjf",
"Image": "nginx",
"ImageVersion": "1.17",
"ServiceName": "test-chow",
"Replicas": 2,
"Networks": [
{
"Target": "chow",
"Aliases": null,
"DriverOpts": null
}
]
}
(2)、全量传参,不报错
{
"ServiceId": "i8cdkcbb4o9ly0nczqlgt5l3l",
"Image": "nginx",
"ImageVersion": "1.17",
"ServiceName": "test-chow",
"Replicas": 2,
"Command": [],
"ContainerEnv": [],
"PortConfig": [
{
"Protocol": "tcp",
"TargetPort": 80,
"PublishedPort": 8082
}
],
"Networks": [
{
"Target": "chow",
"Aliases": null,
"DriverOpts": null
}
],
"UpdateConfig": {
"Parallelism": 1,
"Delay": 10000000000,
"FailureAction": "",
"Monitor": null,
"MaxFailureRatio": 0,
"Order": null
},
"RollbackConfig": {
"Parallelism": null,
"Delay": 10000000000,
"FailureAction": null,
"Monitor": null,
"MaxFailureRatio": 0,
"Order": ""
},
"RestartPolicy": {
"Condition": null,
"Delay": null,
"MaxAttempts": null
},
"WarehouseUrl": null,
"WarehousePwd": null,
"WarehouseUserName": null,
"Mount": []
}
2. 更新的时候,不传network参数,相当于移除network
(1)部分传参,报错
{
"ServiceId": "tx8882z81lh834uenw4tcgt48",
"Image": "nginx",
"ImageVersion": "1.17",
"ServiceName": "test-chow",
"Replicas": 2
}
(2)全量传参,不报错(参数太多,博客省略部分,实际传参的时候有)
{
"ServiceId": "uvknv24zb8q2iouoz9lv5v13n",
"Image": "nginx",
"ImageVersion": "1.17",
"ServiceName": "test-chow",
"Replicas": 2,
"Command": [],
"ContainerEnv": [],
"PortConfig": [
{
"Protocol": "tcp",
"TargetPort": 80,
"PublishedPort": 8082
}
],
....省略
}
3. 更新的时候,传network,但是是添加network
(1)部分传参,报错
{
"ServiceId": "aqp2b7cmrh5egjezenuf0vx6r",
"Image": "nginx",
"ImageVersion": "1.17",
"ServiceName": "test-chow",
"Replicas": 2,
"Networks": [
{
"Target": "chow",
"Aliases": null,
"DriverOpts": null
},
{
"Target": "my-net",
"Aliases": null,
"DriverOpts": null
}
]
}
(2)全量传参,不报错
{
"ServiceId": "bn0k9vxspi98m8qz9ceh14jc1",
"Image": "nginx",
"ImageVersion": "1.17",
"ServiceName": "test-chow",
"Replicas": 2,
"Command": [],
"ContainerEnv": [],
"PortConfig": [
{
"Protocol": "tcp",
"TargetPort": 80,
"PublishedPort": 8082
}
],
"Networks": [
{
"Target": "chow",
"Aliases": null,
"DriverOpts": null
},
{
"Target": "my-net",
"Aliases": null,
"DriverOpts": null
}
],
...省略
}
4. 更新的时候,传network,但是是移除一个network
(1)部分传参,报错
{
"ServiceId": "5k0nt8l45nbycxpzb0o5gzy38",
"Image": "nginx",
"ImageVersion": "1.17",
"ServiceName": "test-chow",
"Replicas": 2,
"Networks": [
{
"Target": "chow",
"Aliases": null,
"DriverOpts": null
}
]
}
(2)全量传参,不报错
{
"ServiceId": "21ixmxc0xvh4s0t2jr1ke1ofl",
"Image": "nginx",
"ImageVersion": "1.17",
"ServiceName": "test-chow",
"Replicas": 2,
"Command": [],
"ContainerEnv": [],
"PortConfig": [
{
"Protocol": "tcp",
"TargetPort": 80,
"PublishedPort": 8082
}
],
"Networks": [
{
"Target": "chow",
"Aliases": null,
"DriverOpts": null
}
],
...省略
}
{
"ServiceId": "ldpoqhv2yufff7i7ulqutii9c",
"Image": "nginx",
"ImageVersion": "1.17",
"ServiceName": "test-chow",
"Replicas": 2,
"Networks": [
{
"Target": "chow",
"Aliases": null,
"DriverOpts": null
}
],
"UpdateConfig": {
"Parallelism": 1,
"Delay": 10000000000,
"FailureAction": "",
"Monitor": null,
"MaxFailureRatio": 0,
"Order": null
}
}
5. 创建的时候,不全两传参且不设置network,更新的时候,完全没问题,即使更新的时候不穿UpdateConfig参数
[{
"Image": "nginx",
"ImageVersion": "1.17",
"ServiceName": "test-chow",
"Replicas": 3
}]
{
"ServiceId": "vi7y48jxaj05h2w0vjnpb3oi0",
"Image": "nginx",
"ImageVersion": "1.17",
"ServiceName": "test-chow",
"Replicas": 2
}
6. 创建service的时候不全传,但参设置network,不设置UpdateConfig
1. 更新的时候不传network和UpdateConfig,报错
[{
"Image": "nginx",
"ImageVersion": "1.17",
"ServiceName": "test-chow",
"Replicas": 3,
"Networks": [
{
"Target": "chow",
"Aliases": null,
"DriverOpts": null
},
{
"Target": "my-net",
"Aliases": null,
"DriverOpts": null
}
]
}]
{
"ServiceId": "t7f637mq0e3cpczdtrrjm72kf",
"Image": "nginx",
"ImageVersion": "1.17",
"ServiceName": "test-chow",
"Replicas": 2
}
2. 更新的时候不传network,传UpdateConfig,不报错
[{
"Image": "nginx",
"ImageVersion": "1.17",
"ServiceName": "test-chow",
"Replicas": 3,
"Networks": [
{
"Target": "chow",
"Aliases": null,
"DriverOpts": null
},
{
"Target": "my-net",
"Aliases": null,
"DriverOpts": null
}
]
}]
{
"ServiceId": "6vlve54skeq2odj5py4aign3f",
"Image": "nginx",
"ImageVersion": "1.17",
"ServiceName": "test-chow",
"Replicas": 2,
"UpdateConfig": {
"Parallelism": 1,
"Delay": 10000000000,
"FailureAction": "",
"Monitor": null,
"MaxFailureRatio": 0,
"Order": null
}
}
