x11docker how to restart my docker

[showfuture]

when I run this code "read Xenv < <(x11docker --gpu --runtime=nvidia --hostdisplay --showenv --home=/work_log --pull=yes --name=unity3d-job unity3d-job:20220407-28)", my container always down, how can I auto restart my container!

[showfuture]

like docker run -d --restart=always

There is no option to automatically restart x11docker. If your application crashes, it makes sense to check and fix the issue that leads to a crash.

You could run a loop like:

while :; do
  read Containerid < <(x11docker --showid --gpu --runtime=nvidia --hostdisplay --home=/work_log --pull=yes --name=unity3d-job unity3d-job:20220407-28
  docker logs -f $Containerid >/dev/null 2>/&1
done

Or just:

while :; do
  x11docker --showid --gpu --runtime=nvidia --hostdisplay --home=/work_log --pull=yes --name=unity3d-job unity3d-job:20220407-28
done

I found this log, I see ' watchpidlist(): PID 10637 has terminated' and 'Removing container unity3d-job', Why did it happen

[mviereck]

I found this log, I see ' watchpidlist(): PID 10637 has terminated' and 'Removing container unity3d-job', Why did it happen

It seems that the container starts, but your container application exits very soon. In that case x11docker terminates, too. PID 10637 is mentioned above as pid1pid=10637, so it is the first pid of the container. Do you get any terminal output from your application?

Btw., it seems that you use an old x11docker version. For further debugging, please update with x11docker --update or x11docker --update-master.

[showfuture]

when I run this shell:

#!/bin/bash
while true
do

        read xenv < \<\( /usr/bin/x11docker --gpu --runtime=nvidia --hostdisplay --showenv --home=/extra_work_log --pull=yes --name=$DOCKER_NAME $REGISTRY_PULL_HOST/bigdata/unity3d-job:$BUILD_VERSION\)
done

it's show wrong message :

/root/deploy/test.sh:行6: <(/usr/bin/x11docker: 没有那个文件或目录

how to fix this err

[mviereck]

You should not escape the code:

\<\(

\)

Without \ it should work:

#!/bin/bash
while true
do

        read xenv < <( /usr/bin/x11docker --gpu --runtime=nvidia --hostdisplay --showenv --home=/extra_work_log --pull=yes --name=$DOCKER_NAME $REGISTRY_PULL_HOST/bigdata/unity3d-job:$BUILD_VERSION)
done

Note: You'll run an infinite number of containers with this loop! x11docker is moved to background, so the loop will immediately run x11docker again.

However, rather than using a loop find out why your application crashes and fix that. Does it print any error messages?

---

Did you update x11docker? The current version is 7.1.4, compare x11docker --version.

[showfuture]

my completed shell script is ：

#!/bin/bash

DOCKER_NAME=$1
REGISTRY_PULL_HOST=$2
STATUS=$3
BUILD_VERSION=$4

echo "$DOCKER_NAME"
echo "$REGISTRY_PULL_HOST"
echo "$STATUS"
echo "$BUILD_VERSION"

while true
do
    echo "a"
    if [[ $STATUS == "stop" ]];then
    echo "111ss"
        sh /root/deploy/stop.sh
    echo "stopped"
        break
    elif [[ -n $(docker ps -q -f "name=$DOCKER_NAME") ]];then
    echo "ssss"
        echo -e "`date` \ncontainer $DOCKER_NAME is running" > /extra_work_log/deploy.log
    else
    echo "222sss"
        echo "read Xenv < <(x11docker --gpu --runtime=nvidia --hostdisplay --showenv --home=/extra_work_log --pull=yes --name=$DOCKER_NAME $REGISTRY_PULL_HOST/bigdata/unity3d-job:$BUILD_VERSION)"
        read xenv < \<\( /usr/bin/x11docker --gpu --runtime=nvidia --hostdisplay --showenv --home=/extra_work_log --pull=yes --name=$DOCKER_NAME $REGISTRY_PULL_HOST/bigdata/unity3d-job:$BUILD_VERSION\)

        echo -e "`date` \ncontainer $DOCKER_NAME has stopped"  >> /extra_work_log/deploy.log
    fi
    sleep 20
done

so don't worry about "You'll run an infinite number of containers with this loop!"

but if I don't escape the code:

/root/deploy/test.sh:行27: 未预期的符号 `<' 附近有语法错误
/root/deploy/test.sh:行27: `        read xenv < <(/usr/bin/x11docker --gpu --runtime=nvidia --hostdisplay --showenv --home=/extra_work_log --pull=yes --name=$DOCKER_NAME $REGISTRY_PULL_HOST/bigdata/unity3d-job:$BUILD_VERSION)'

so what can I do?

I don't update x11docker, if I update x11docker, I must change mysql total code! my x11docker version is "6.10.0"

[showfuture]

my completed shell script is ：

#!/bin/bash

DOCKER_NAME=$1
REGISTRY_PULL_HOST=$2
STATUS=$3
BUILD_VERSION=$4

echo "$DOCKER_NAME"
echo "$REGISTRY_PULL_HOST"

while true
do
    echo "a"
    if [[ $STATUS == "stop" ]];then
    echo "111ss"
        sh /root/deploy/stop.sh
    echo "stopped"
        break
    elif [[ -n $(docker ps -q -f "name=$DOCKER_NAME") ]];then
    echo "ssss"
        echo -e "`date` \ncontainer $DOCKER_NAME is running" > /extra_work_log/deploy.log
    else
    echo "222sss"
        echo "read Xenv < <(x11docker --gpu --runtime=nvidia --hostdisplay --showenv --home=/extra_work_log --pull=yes --name=$DOCKER_NAME $REGISTRY_PULL_HOST/bigdata/unity3d-job:$BUILD_VERSION)"

        echo -e "`date` \ncontainer $DOCKER_NAME has stopped"  >> /extra_work_log/deploy.log
    fi
    sleep 20
done

so don't worry about "You'll run an infinite number of containers with this loop!"

but if I don't escape the code:

Maybe you run the script with sh script.sh? Than the script would be executed by sh instead of bash. The syntax with < <(...) is specific to bash, but does not work in sh.

Try to run the command without \ in a bash shell.
