Multiple known_hosts

[ghost]

@AnticliMaxtic commented on Jun 1, 2019, 4:01 PM UTC:

It does not seem to be possible to use a known_hosts file rather than a string for a single known hosts. I have multiple servers that I need the same ssh key to authenticate against and I have put them all in together as one string, but that does not seem to work. I can only access the first one in the list

Does a yaml multiline string help?

[yahalawa]

@berney no it does not i tried that

[natebunton]

Any update on this?

[natebunton]

I was able to work around this by using powershell task after the InstallSSHKey task to add-content to the ~.ssh\known_hosts file:

`

• task: PowerShell@2 displayName: 'Powershell - Add known_hosts' inputs: targetType: 'inline' script: 'Add-Content -Path "~.ssh\known_hosts" -Value "ADD YOUR KNOWN HOSTS ENTRY HERE"'

`

[tylersouthard]

I ran into this as well. The workaround works OK, but it's dicey to do on Windows when the agent is running as the Network Service user...

The task really needs to support multiple known host entries.

[AnticliMaxtic]

@Microsoft Any progress on this issue?

@natebunton, your solution has un-stuck us, but a cleaner solution is still desirable

[SamYuan1990]

Some update here.

I want to start a docker container, as myContainer with port 8080 exported. Then starts test code as curl myContainer:8080

The container doesn't have ssh support, so ... what I excepted is that on /etc/hosts having myContainer 127.0.0.1

So that can avoid myContainer, host not found

[ekaterina-tatanova]

Hello, @AnticliMaxtic, @yahalawa, @berney, @natebunton, @tylersouthard! Using txf-cli, upload the patch from attachments. To do that use these instructions. Upload command example: tfx build tasks upload -u https://<YOUR_ORGANISATION>.visualstudio.com/DefaultCollection -t <YOUR_PERSONAL_ACCESS_TOKEN> --task-path <PATH_TO_TASK> Then replace the task in .yaml file to InstallSSHKeyMultilineHostEntryV0. Please, let us know if it works for you or if you have any questions. Hopefully, I will fix it in the next release.

[SamYuan1990]

So I am now able to use in azure-pipeline? or is there any sample to use it?

myContainer 127.0.0.1

@SamYuan1990 The changes are not depoyed yet. If it's necessary to use it now, you may deploy the changed task to your organization like it's described in the comment above.

[fluffy-cakes]

@ekaterina-tatanova , I can see you have merged the changes in. do you know an eta for when that would be generally available to use?

[ekaterina-tatanova]

@fluffy-cakes Hopefully by the end of the next week.

[SamYuan1990]

@SamYuan1990 The changes are not depoyed yet. If it's necessary to use it now, you may deploy the changed task to your organization like it's described in the comment above.

ok， pls let me know once it ready.

[ekaterina-tatanova]

@fluffy-cakes @SamYuan1990 The changes will be available in 2-3 weeks.

[ekaterina-tatanova]

@fluffy-cakes @SamYuan1990 The changes were deployed in the latest release.

[fluffy-cakes]

@ekaterina-tatanova Can you please advise how to use this new version? InstallSSHKey@0 was the old non-working task, and updating to InstallSSHKey@1 makes no difference.

Comparing a run from last month, I can see no difference in the version of the task being updated, and still won't function as intended.

Going back mid June and earlier, I can see some jobs running v0.170.1. However the issue of not being able to identify and check out two repos from GitHub doesn't work. Perhaps it is me that's doing it wrong, but can you please identify what the version was before, and what it should be now.

[ekaterina-tatanova]

@fluffy-cakes Do you store known_hosts input as variable? Could you please share your yaml file?

[SamYuan1990]

can someone update here: https://docs.microsoft.com/zh-cn/azure/devops/pipelines/migrate/from-travis?view=azure-devops can't find out sample for how to use it.

[fluffy-cakes]

@fluffy-cakes Do you store known_hosts input as variable? Could you please share your yaml file?

@ekaterina-tatanova Since this ticket was closed, I raised another; https://github.com/microsoft/azure-pipelines-tasks/issues/13283

Hopefully you have all the details you need in there.

[keithatisoplexis]

@ekaterina-tatanova There is still no documentation of InstallSSHKeyMultilineHostEntryV0 anywhere. Did this task type get removed?
