[bug] didn't reconnect the docker socket

when docker is restarted, should reconnect the docker sock, since there are maybe a "live-restore" config, so that the process will not stop when restarting the docker daemon.

[feature request] tail logs online

for some reasons we cannot exec docker or the exec it not convenient, so we want to tail container logs via the browser, arguments available.

Disable terminals

Hello, is there any way to disable the terminals and only provide the logs?

Something wrong with using iframes

we use iframes to place several containers on 1 page, but there are some errors
opening the container in a separate tab - all works fine

iframes code (nothing unusual)

List container filter, default running, not all

--all options

backend get sh

// cat /etc/shells` and chose one
GetShell(containerID string) string

feat: update container list triggered by events

only update container storage when something happens, such as "docker create", "docker restart", "docker run" and so on.

feature request: [re]start button

start/restart the container
add status column

Lost connection to docker socket

After the recent update on 25/9, the container lost connection to the docker sock. I tried using the volume mount and the proxy socket, but none worked.
Previously, I used to have it running using the socket proxy

Below is the docker-compose and log using the volume mounting /var/run/docker.sock

Upgrade dependency "github.com/gin-gonic/gin"

Background

Repo github.com/wrfly/container-web-tty depends on github.com/gin-gonic/[email protected].

https://github.com/wrfly/container-web-tty/blob/master/go.mod#L10

However, comparing version v1.7.3 of github.com/gin-gonic/gin from proxy.golang.org and github, there are inconsistencies.

commit time of the copy on github.com

"committer": {
      "name": "Bo-Yi Wu",
      "email": "[email protected]",
      "date": "2021-08-03T02:40:44Z"
    }

commit time of the copy on proxy.golang.org

"Version":"v1.7.3","Time":"2021-08-03T02:36:43Z"}

So the checksum from the code in github does not match the checksum saved in sum.golang.org. The v1.7.3 tag of github.com/gin-gonic/gin might have been retagged after a minor edition on github. I guess you use proxy.golang.org to get dependencies, but that also shows that your project is depending on the copy of github.com/gin-gonic/[email protected] before its edition. Depending upon such inconsistent tag version may also result in some unexpected errors as well as build errors due to different proxy settings.

For example, when someone who does not use proxy.golang.org, say GOPROXY=direct, attempts to get github.com/gin-gonic/[email protected], the following error occurs.

go: downloading github.com/gin-gonic/gin v1.7.3
go: github.com/gin-gonic/gin@v1.7.3: verifying module: checksum mismatch

SECURITY ERROR
This download does NOT match the one reported by the checksum server.
The bits may have been replaced on the origin server, or an attacker may
have intercepted the download attempt.

For more information, see 'go help module-auth'.

So, this is a reminder in the hope that you can get rid of this problematic version of project github.com/gin-gonic/gin.

Solution

1. Bump the version of dependency `github.com/gin-gonic/gin`

I would recommend bumping the version of github.com/gin-gonic/gin to a new release to ensure dependency copy in proxy.golang.org and github in sync.

Sometimes we can only connect the server via the proxy.

feature request: add container name to title

重构完成之后，在web page的title中添加container的name

"mesg: ttyname failed: No such device"

the message "mesg: ttyname failed: No such device" or "mesg: ttyname failed: Success" comes from /root/.profile : mesg n || true

fix: exec cmd panic

sometimes the command contains ", and the exec will panic

我们在使用[container-web-tty]的时候，终端基本访问2到3分钟就会中断一次，下面是docker中输出日志的截图

这行貌似应该删掉？另外 kuberctl >> kubectl

use print instead, do not format it.

Question about CMD

Hello,

I have some kind of project on mind which i'm thinking to run under docker containers,

So i also need to provide to my users access via console(tty), so randomly found this project and it looks interesting, however (since i can't install this atm) i have a question

How does this attach console into the browser my question exactly is example if we start a docker container with a cmd to run some app, apache nginx or whatever when you do docker exec -it container1 bash you'll see the running appoutput (output of nginx or apache)
so what output will container-web-tty display?
the same as docker exec -it... or nothing like you just connect via ssh to a server with a new session?

Thanks
