Localised example. Steps to reproduce:
docker run -itd busybox cat
curl --cert cert.pem --key key.pem --cacert ca.pem \
https://192.168.99.100:2376/containers/${CONTAINER_ID}/exec \
-H "Content-Type: application/json" \
-X POST \
--data @exec.json
exec.json:
{
"AttachStderr": true,
"AttachStdin": true,
"AttachStdout": true,
"Cmd": [
"/bin/bash",
"-cxe",
"cat << EOF > /tmp/config.sh.tmp && cd /tmp && mv config.sh.tmp config.sh\n sdf\nEOF\n"
]
}
curl --cert cert.pem --key key.pem --cacert ca.pem \
https://192.168.99.100:2376/exec/${EXEC_ID}/start \
-H "Content-Type: application/json" \
-X POST \
--data @start.json
start.json:
{
"Detach": true,
"Tty": true
}
Combination may be crazy, but i expect that daemon should survive.
